TheÂ iPhoneÂ is a line ofÂ smartphonesÂ designed and marketed byÂ Apple Inc.Â All generations of the iPhone use Apple’sÂ iOSÂ mobile operating system software. TheÂ first-generation iPhoneÂ was released on June 29, 2007, and multiple new hardware iterations with new iOS releases have been released since.
TheÂ user interfaceÂ is built around the device’sÂ multi-touchÂ screen, including aÂ virtual keyboard. The iPhone hasÂ Wi-FiÂ and can connect toÂ cellular networks. An iPhone canÂ take photos,Â play music, send and receiveÂ emails,Â browse the web, send and receiveÂ text messages, record notes, perform mathematical calculations, and receiveÂ visual voicemail.Â Shooting videoÂ also became a standard feature with theÂ iPhone 3GS. Other functionality, such as video games, reference works, and social networking, can be enabled by downloadingÂ mobile apps. As of JanuaryÂ 2017, Apple’sÂ App StoreÂ contained more than 2.2Â million applications available for the iPhone.
Apple has released thirteenÂ generationsÂ of iPhone models, each accompanied by one of the thirteen major releases of theÂ iOSÂ operating system. TheÂ first-generation iPhoneÂ was aÂ GSMÂ phone and established design precedents, such as a placement of certain buttons that has persisted throughout all releases to date. The first iPhone also set a screen size that was maintained for the next four iterations. TheÂ iPhone 3GÂ addedÂ 3GÂ network support and was followed by theÂ iPhone 3GSÂ with improved hardware, theÂ iPhone 4Â with a metal chassis, higher display resolution, and front-facing camera, and theÂ iPhone 4SÂ with improved hardware and the voice assistantÂ Siri. TheÂ iPhone 5Â featured a taller, 4 inches (100Â mm) display and Apple’s newly introducedÂ Lightning connector. In 2013, Apple released theÂ iPhone 5SÂ with improved hardware and aÂ fingerprint readerÂ (marketed as ‘Touch ID’), and the lower-costÂ iPhone 5C, a version of the 5 with a plastic body, instead of metal one. The 5C was also available in many colors. They were followed by the largerÂ iPhone 6 and iPhone 6 Plus, with models featuring 4.7-and-5.5-inch (120 and 140Â mm) displays. TheÂ iPhone 6SÂ was introduced the following year, which featured hardware upgrades and support forÂ pressure-sensitive touch inputs, as well as theÂ iPhone SEâ€”which featured hardware from the 6S but the smaller form factor of the 5S. In 2016, Apple unveiled theÂ iPhone 7 and iPhone 7 Plus, which add water resistance, improved system, and graphics performance, a new rear dual-camera setup on the Plus model, and new color options, while removing the 3.5Â mm headphone jack found on previous models. TheÂ iPhone 8 and iPhone 8 PlusÂ were released in 2017, adding a glass back and an improved screen and camera. TheÂ iPhone XÂ was released alongside the iPhone 8 and iPhone 8 Plus, with its highlights being a near bezel-less design, an improved camera, and a new facial recognition system, namedÂ Face ID, but having no home button, and therefore, noÂ Touch ID. In September 2018, Apple released 3 new iPhones, which are theÂ iPhone XS, an upgraded version of the since discontinued iPhone X,Â iPhone XS Max, a larger variant with the series’ biggest display as of 2018Â andÂ iPhone XR, a lower-end version of the iPhone X. On September 10, 2019, Apple again released 3 new iPhones, which areÂ iPhone 11 Pro,Â iPhone 11 Pro Max, and the lower-endÂ iPhone 11. On April 15, 2020, Apple announced the second-generationÂ iPhone SEÂ as a successor to both the original iPhone SE and the iPhone 8, featuring hardware from the 11 and 11 Pro in a design nearly identical to the iPhone 8.
The first-generation iPhone was described as “revolutionary” and a “game-changer” for the mobile phone industry. Subsequent iterations of the iPhone have also garnered praise. The iPhone is one of the most widely used smartphones in the world, and its success has been credited with helping Apple become one of the world’sÂ most valuable publicly traded companies.
As of November 1, 2018, more than 2.2 billion iPhones had been sold.

Development of what was to become the iPhone began in 2004, when Apple started to gather a team of 1,000 employees (includingÂ Jonathan Ive, the designer behind the iMac and iPod)Â to work on the highly confidential “Project Purple.”Â Apple CEOÂ Steve JobsÂ steered the original focus away from a tablet (which Apple eventually revisited in the form of theÂ iPad) towards a phone.Â Apple created the device during a secretive collaboration with Cingular Wireless (which becameÂ AT&T Mobility) at the timeâ€”at an estimated development cost of US$150Â million over thirty months.
Apple rejected the “design by committee” approach that had yielded theÂ Motorola ROKR E1, a largely unsuccessful collaboration withÂ Motorola. Among other deficiencies, the ROKR E1’s firmware limited storage to only 100Â iTunesÂ songs to avoid competing with Apple’sÂ iPod nano.
Cingular gave Apple the liberty to develop the iPhone’s hardware and software in-houseÂ and even paid Apple a fraction of its monthly service revenue (until the iPhone 3G),Â in exchange for four years of exclusive U.S. sales, until 2011.
Jobs unveiled theÂ iPhoneÂ to the public on January 9, 2007, at theÂ MacworldÂ 2007 convention at theÂ Moscone CenterÂ in San Francisco.Â The two initial models, a 4Â GB model priced at US$499 and an 8Â GB model at US$599 (both requiring a two-year contract), went on sale in the United States on June 29, 2007, at 6:00Â pm local time, while hundreds of customers lined up outside the stores nationwide.Â The passionate reaction to the launch of the iPhone resulted in sections of the media dubbing it the ‘Jesus phone’.Â Following this successful release in the US, the first generation iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008.
On July 11, 2008, Apple released theÂ iPhone 3GÂ in twenty-two countries, including the original six.Â Apple released the iPhone 3G in upwards of eighty countries and territories.Â Apple announced theÂ iPhone 3GSÂ on June 8, 2009, along with plans to release it later in June, July, and August, starting with the US, Canada and major European countries on June 19. Many would-be users objected to the iPhone’s cost,Â and 40% of users had household incomes over US$100,000.
The back of the original first-generation iPhone was made of aluminum with a black plastic accent. The iPhone 3G and 3GS feature a full plastic back to increase the strength of theÂ GSMÂ signal.Â The iPhone 3G was available in an 8Â GB black model, or a black or white option for the 16Â GB model. The iPhone 3GS was available in both colors, regardless of storage capacity.
The iPhone 4 has anÂ aluminosilicateÂ glass front and back with aÂ stainless steelÂ edge that serves as theÂ antennas. It was at first available in black; the white version was announced, but not released until April 2011, 10 months later.
On January 11, 2011,Â VerizonÂ announced during a media event that it had reached an agreement with Apple and would begin selling aÂ CDMAÂ iPhone 4. Verizon said it would be available for pre-order on February 3, with a release set for February 10.Â In February 2011, the Verizon iPhone accounted for 4.5% of all iPhoneÂ ad impressionsÂ in the U.S. on Millennial Media’s mobile ad network.
From 2007 to 2011, Apple spent $647Â million on advertising for the iPhone in the US.
On Tuesday, September 27, Apple sent invitations for a press event to be held October 4, 2011, at 10:00Â am at theÂ CupertinoÂ headquarters to announce details of the next generation iPhone, which turned out to beÂ iPhone 4S. Over 1Â million 4S models were sold in the first 24 hours after its release in October 2011.Â Due to large volumes of the iPhone being manufactured and its high selling price, Apple became the largest mobile handset vendor in the world by revenue, in 2011, surpassing long-time leaderÂ Nokia.Â American carrierÂ C Spire WirelessÂ announced that it would be carrying the iPhone 4S on October 19, 2011.
In January 2012, Apple reported its best quarterly earnings ever, with 53% of its revenue coming from the sale of 37Â million iPhones, at anÂ average selling priceÂ of nearly $660. The average selling price has remained fairly constant for most of the phone’s lifespan, hovering between $622 and $660.Â The production price of the iPhone 4S was estimated byÂ IHS iSuppli, in October 2011, to be $188, $207 and $245, for the 16Â GB, 32Â GB and 64Â GB models, respectively.Â Labor costs are estimated at between $12.50 and $30 per unit, with workers on the iPhone assembly line making $1.78 an hour.
On September 12, 2012, Apple announced the iPhone 5. It has a 4 inches (100Â mm) display, up from its predecessors’ 3.5 inches (89Â mm) screen. The device comes with the same 326 pixels per inch found in the iPhone 4 and 4S. The iPhone 5 has theÂ SoCÂ A6 processor, the chip is 22% smaller than the iPhone 4S’ A5 and is twice as fast, doubling the graphics performance of its predecessor. The device is 18% thinner than the iPhone 4S, measuring 7.6 millimetres (0.3Â in), and is 20% lighter at 112 grams (4Â oz).
On July 22, 2013, the company’s suppliers said that Apple is testing out larger screens for the iPhone and iPad. “Apple has asked for prototype smartphone screens larger than 4 inches (100Â mm) and has also asked for screen designs for a new tablet device measuring slightly less than 13 inches (330Â mm) diagonally, they said.”
On September 10, 2013, Apple unveiled two new iPhone models during a highly anticipated press event in Cupertino. The iPhone 5C, a mid-range-priced version of the handset that is designed to increase accessibility due to its price is available in five colors (green, blue, yellow, pink, and white) and is made of plastic. The iPhone 5S comes in three colors (black, white, and gold) and the home button is replaced with a fingerprint scanner (Touch ID). Both phones shipped on September 20, 2013.
On September 9, 2014, Apple revealed the iPhone 6 and the iPhone 6 Plus at an event in Cupertino. Both devices had a larger screen than their predecessor, at 4.7 inches (120Â mm) and 5.5 inches (140Â mm) respectively.
In 2016, Apple unveiled theÂ iPhone 7 and 7 Plus, which added water and dust resistance, improved system and graphics performance, a new dual-camera setup on the Plus model, new color options, and featured the removal of the 3.5Â mm headphone jack from the iPhone.
On September 12, 2017, Apple officially unveiled the iPhone 8 and 8 Plus, which features a new glass design, camera improvements, a True Tone display, wireless charging, and improved system performance. It also unveiled the iPhone X, which features a near bezel-less design, a facial recognition feature dubbed “Face ID” with facial tracking used for Animojis, an OLED screen with the highest pixel density on an iPhone, a new telephoto lens which works better in low light conditions, and improved cameras for AR.
On September 12, 2018, Apple officially unveiled the iPhone XS, XS MaxÂ and XRÂ at the Steve Jobs theater atÂ Apple Park. The XS and XS Max feature an improved Super Retina Display with Dolby Vision and HDR10 support with the XS Max featuring a larger 6.5 inches (170Â mm) display, improved cameras with Smart HDR, and the A12 Bionic chip. The iPhone XS and XS Max areÂ IP68Â water, liquid, and dust resistant which allow the devices to be submerged in up to 2 meters for a duration of 30 minutes, while iPhone XR retained the IP67 certification found in the first-generation iPhone X and also features an IPS LCD display instead of the OLED displays found in the higher-end models. The iPhone XS/XS Max’s IP68 certifications were tested using variousÂ liquidsÂ such asÂ chlorinated-water, saltwater,Â tea,Â wine,Â beer, andÂ juices. Apple also announced the fourth generation of Apple Watch, theÂ Apple Watch Series 4.
Apple sold 6.1Â million first generation iPhone units over five quarters.Â Sales in the fourth quarter of 2008 temporarily surpassed those ofÂ Research In Motion‘s (RIM)Â BlackBerryÂ sales of 5.2Â million units, which briefly made Apple the third largest mobile phone manufacturer by revenue, afterÂ NokiaÂ andÂ SamsungÂ (however, some of this income isÂ deferred). Recorded sales grew steadily thereafter, and by the end ofÂ fiscal yearÂ 2010, a total of 73.5Â million iPhones had been sold.
By 2010, the iPhone had a market share of barely 4% of all cell phones; however, Apple pulled in more than 50% of the total profit that global cellphone sales generated.Â Apple sold 14.1Â million iPhones in the third quarter of 2010, representing a 91% unit growth over the year-ago quarter, which was well ahead ofÂ IDC‘s latest published estimate of 64% growth for the global smartphone market in the September quarter. Apple’s sales surpassed that ofÂ Research in Motion‘s 12.1Â millionÂ BlackBerryÂ units sold in their most recent quarter ended August 2010.Â In the United States market alone for the third quarter of 2010, while there were 9.1Â million Android-powered smartphones shipped for 43.6% of the market, Apple iOS was the number two phone operating system with 26.2% but the 5.5Â million iPhones sold made it the most popular single device.
On March 2, 2011, at theÂ iPad 2Â launch event, Apple announced that they had sold 100Â million iPhones worldwide.Â As a result of the success of the iPhone sales volume and high selling price, headlined by theÂ iPhone 4S, Apple became the largest mobile handset vendor in the world by revenue in 2011, surpassing long-time leaderÂ Nokia.Â While theÂ Samsung Galaxy S IIÂ proved more popular than the iPhone 4S in parts of Europe, the iPhone 4S was dominant in the United States.
In January 2012, Apple reported its best quarterly earnings ever, with 53% of its revenue coming from the sale of 37Â million iPhones, at anÂ average selling priceÂ of nearly $660. The average selling price has remained fairly constant for most of the phone’s lifespan, hovering between $622 and $660.
For the eight largest phone manufacturers in Q1 2012, according toÂ Horace DediuÂ at Asymco, Apple and Samsung combined to take 99% of industry profits (HTC took the remaining 1%, while RIM, LG, Sony Ericsson, Motorola, and Nokia all suffered losses), with Apple earning 73 cents out of every dollar earned by the phone makers. As the industry profits grew from $5.3Â billion in the first quarter of 2010 to $14.4Â billion in the first quarter of 2012 (quadruple the profits in 2007),Â Apple had managed to increase its share of these profits. This is due to increasing carrier subsidies and the high selling prices of the iPhone, which had a negative effect on the wireless carriers (AT&T Mobility, Verizon, and Sprint) who have seen their EBITDA service margins drop as they sold an increasing number of iPhones.Â By the quarter ended March 31, 2012, Apple’s sales from the iPhone alone (at $22.7Â billion) exceeded the total ofÂ MicrosoftÂ from all of its businesses ($17.4Â billion).
In the fourth quarter of 2012, theÂ iPhone 5Â andÂ iPhone 4SÂ were the best-selling handsets with sales of 27.4Â million (13% of smartphones worldwide) and 17.4Â million units, respectively, with theÂ Samsung Galaxy SÂ IIIÂ in third with 15.4Â million. According to Strategy Analytics’ data, this was “an impressive performance, given the iPhone portfolio’s premium pricing”, adding that the Galaxy SÂ III’s global popularity “appears to have peaked” (the Galaxy SÂ III was touted as an iPhone-killer by some in the press when it was released). While Samsung has led in worldwide sales of smartphones, Apple’s iPhone line has still managed to top Samsung’s smartphone offerings in the United States,Â with 21.4% share and 37.8% in that market, respectively. iOS grew 3.5% to 37.8%, while Android slid 1.3% to fall to a 52.3% share.
The continued top popularity of the iPhone despite growing Android competition was also attributed to Apple being able to deliverÂ iOSÂ updates over the air, whileÂ AndroidÂ updates are frequently impeded by carrier testing requirements and hardware tailoring, forcing consumers to purchase a new Android smartphone to get the latest version of that OS.Â However, by 2013, Apple’s market share had fallen to 13.1%, due to the surging popularity of the Android offerings.
Apple announced on September 1, 2013, that its iPhone trade-in program would be implemented at all of its 250 specialty stores in the US. For the program to become available, customers must have a valid contract and must purchase a new phone, rather than simply receive a credit to be used at a later date. A significant part of the program’s goal is to increase the number of customers who purchase iPhones at Apple stores rather than carrier stores.
On September 20, 2013, the sales date of the iPhone 5S and 5C models, the longest ever queue was observed at the New York City flagship Apple store, in addition to prominent queues in San Francisco, and Canada; however, locations throughout the world were identified for the anticipation of corresponding consumers.Â Apple also increased production of the gold-colored iPhone 5S by an additional one-third due to the particularly strong demand that emerged.Â Apple had decided to introduce a gold model after finding that gold was seen as a popular sign of a luxury product amongÂ ChineseÂ customers.
Apple released its opening weekend sales results for the 5C and 5S models, showing an all-time high for the product’s sales figures, with nineÂ million handsets soldâ€”the previous record was set in 2012, when fiveÂ million handsets were sold during the opening weekend of the 5 model. This was the first time that Apple has simultaneously launched two models and the inclusion of China in the list of markets contributed to the record sales result.Â Apple also announced that, as of SeptemberÂ 23, 2013, 200Â million devices were running the iOS 7 update, making it the “fastest software upgrade in history.”
AnÂ Apple StoreÂ located at theÂ Christiana MallÂ inÂ Newark, Delaware, claimed the highest iPhones sales figures in November 2013. The store’s high sales results are due to the absence of aÂ sales taxÂ in the state ofÂ Delaware.
The finalization of a deal between Apple and China Mobile, the world’s largest mobile network, was announced in late December 2013. The multi-year agreement provides iPhone access to over 760Â million China Mobile subscribers.
iPhone Upgrade Program
The iPhone Upgrade Program is a 24-month program designed for consumers to be able to get the latest iPhone every year, without paying the whole price up-front. The program consists of “low monthly payments”, where consumers will gradually pay for the iPhone they have over a 24-month period, with an opportunity to switch (upgrade) to the new iPhone after 12 months of payment have passed. Once 12 months have passed, consumers can trade their current iPhone with a new one, and the payments are transferred from the old device to the new device, and the program “restarts” with a new 24-month period.
Additional features of the program include unlocked handsets, which means consumers are free to pick the network carrier they want, and two-year AppleCare+ protection, which includes “hardware repairs, software support, and coverage for up to two incidents of accidental damage”.
Criticism of the program includes the potential endless cycle of payments, withÂ The Huffington Post‘s Damon Beres writing, “Complete the full 24-month payment cycle, and you’re stuck with an outdated phone. Upgrade every 12 months, and you’ll never stop owing Apple money for iPhones”. Additionally, the program is limited to just the iPhone hardware; cell phone service from a network operator is not included.
Before the release of the iPhone, handset manufacturers such asÂ NokiaÂ andÂ MotorolaÂ were enjoying record sales ofÂ cell phonesÂ based more on fashion and brand rather than technological innovation.Â The smartphone market, dominated at the time byÂ BlackBerry OSÂ andÂ Windows MobileÂ devices, was a “staid, corporate-led smartphone paradigm” focused on enterprise needs. Phones at the time were designed around carrier and business limits which were conservative with regards to bandwidth usage and battery life.Â Phones were sold in a very large number of models, often segmented by marketing strategy, confusing customers and sapping engineering resources.Â For example, phones marketed at business were often deliberately stripped of cameras or the ability to play music and games.Â Apple’s approach was to deliberately simplify its product line by offering just one model a year for all customers while making it an expensive, high-end product.
Apple’s marketing, developing from the success of iPod campaigns, allowed the phone to become a mass-market product with many buyers on launch day. Some market research has found that, unusually for a technology product, iPhone users are disproportionately female.Â Ars TechnicaÂ noted in 2012 that Apple had avoided ‘patronizing’ marketing to female customers, a practice used (often to sell low-quality, high-priced products) by many of its competitors.
When then-CEO ofÂ Research in MotionÂ Mike LazaridisÂ pried open an iPhone, his impression was of a Mac stuffed into a cellphone, as it used much more memory and processing power than the smartphones on the market at the time.Â With itsÂ capacitive touchscreenÂ and consumer-friendly design, the iPhone fundamentally changed the mobile industry, withÂ Steve JobsÂ proclaiming in 2007, that the phone was not just a communication tool but a way of life.
The dominant mobile operating systems at the time such asÂ Symbian,Â BlackBerry OS, andÂ Windows MobileÂ were not designed to handle additional tasks beyond communication and basic functions. These operating systems never focused on applications and developers, and due to infighting among manufacturers as well as the complexity of developing on their low-memory hardware, they never developed a thriving ecosystem like Apple’sÂ App StoreÂ orÂ Android‘sÂ Google Play.Â iPhone OSÂ (renamed iOS in 2010) was designed as a robust OS with capabilities such as multitasking and graphics in order to meet future consumer demands.Â Many services were provided by mobile carriers, who often extensively customized devices. Meanwhile, Apple’s decision to base its OS onÂ OS XÂ had the unexpected benefit of allowing OS X developers to rapidly expand into iOS development.Â Rival manufacturers have been forced to spend more on software and development costs to catch up to the iPhone. The iPhone’s success has led to a decline in sales of high-end fashion phones and business-oriented smartphones such asÂ VertuÂ andÂ BlackBerry, as well as Nokia.Â Nokia realised the limitations of its operating system Symbian and attempted to develop a more advanced system, Maemo, without success. It ultimately agreed to a technology-sharing deal and then a takeover from Microsoft.
Prior to the iPhone, “Handsets were viewed largely as cheap, disposable lures, massively subsidized to snare subscribers and lock them into using the carriers’ proprietary services.” However, according toÂ Wired, “Apple retained complete control over the design, manufacturing, and marketing of the iPhone”, meaning that it and not the carrier would control the software updates, and by extension security patches. By contrast, Google has allowed carriers and OEMs to dictate the “pace of upgrades and pre-load phones with their own software on top ofÂ Android“. As a result, many Android OEMs often lag months behind Google’s release of the next iteration of Android; although Nexus and Pixel devices are guaranteed two years of operating system updates and a third additional year for security. However, Apple has supported older iterations of iPhones for over four years.
Up to theÂ iPhone 4, all iPhone models, as well as otherÂ iOS devicesÂ were manufactured exclusively byÂ Foxconn, based inÂ Taiwan. In 2011, afterÂ Tim CookÂ became CEO of the company, Apple changed its outsourcing strategy, for the first time increasing its supply partners. TheÂ iPhone 4sÂ in 2012 was the first model which was manufactured simultaneously by two stand-alone companies: Foxconn as well asÂ Pegatron, also based in Taiwan. Although Foxconn is still responsible for the larger share of production, Pegatron’s orders have been slowly increased, with the company being tasked with producing a part of theÂ iPhone 5CÂ line in 2013, and 30% of theÂ iPhone 6Â devices in 2014. The 6 Plus model is being produced solely by Foxconn.Â In 2019, there were reports stating that some of Foxconn’s managers had used rejected parts to build iPhones, and that Apple was investigating the issue.
Screen and input
TheÂ touchscreenÂ on the first five generations is a 3.5 inches (90Â mm)Â liquid crystal displayÂ with scratch-resistant glass; The one on the iPhone 5, 5C, 5S, and first generation SE is 4 inches (100Â mm); The size of the iPhone 6, 6S, 7, 8, and second generation SE is 4.7 inches (120Â mm); the iPhone 6 Plus, 6S Plus, 7 Plus, and 8 Plus is 5.5 inches (140Â mm); The iPhone X, XS, and 11 Pro with 5.8 inches (150Â mm); The iPhone XR, and 11 with 6.1 inches (150Â mm); and the iPhone XS Max and 11 Pro Max with 6.5 inches (170Â mm).Â Â TheÂ capacitive touchscreenÂ is designed for a bare finger, or multiple fingers forÂ multi-touchÂ sensing. The screens on the first three generations have a resolution of 320Ã—480 (HVGA) at 163Â ppi; those on theÂ iPhone 4Â andÂ iPhone 4SÂ have a resolution of 640Ã—960 at 326Â ppi; the 4 inches (100Â mm) models, with 640Ã—1136 at 326Â ppi; the 4.7 inches (120Â mm) models, with 750Ã—1334 at 326Â ppi; the 5.5 inches (140Â mm) models, with 1080Ã—1920 at 401Â ppi; and the 5.8 inches (150Â mm) model X, with 1125Ã—2436 at 458Â ppi. The initial models were usingÂ twisted-nematic (TN) LCDs. Starting with iPhone 4, the technology was changed toÂ in-plane switching (IPS) LCDs. The iPhone 5 model’s screen results in an aspect ratio of approximately 16:9. TheÂ iPhone XÂ is the first iPhone to use anÂ OLEDÂ display. It has a near bezel-less screen with a â‰ˆ19.5:9 aspect ratio.
The touch and gesture features of the iPhone are based on technology originally developed byÂ FingerWorks.Â Most gloves andÂ styliÂ prevent the necessary electrical conductivity;Â althoughÂ capacitive styliÂ can be used with iPhone’s finger-touch screen. The iPhone 3GS and later also feature aÂ fingerprint-resistantÂ oleophobicÂ coating.
The iPhone has a minimal hardware user interface, with most models featuring fiveÂ buttons. The only physical menu button is situated directly below the display and is called the “Home button” because its primary function is to close the active app and navigates to the home screen of the interface. Earlier models included aÂ rounded square, reminiscent of the shape of icons on the home screen, however, new models which include Apple’sÂ fingerprint recognitionÂ featureÂ Touch IDÂ (which use the Home button as the fingerprint sensor) have no symbol. TheÂ iPhone XÂ and later with the exception of theÂ iPhone SE (2nd generation)Â don’t have a Home button but insteadÂ Face ID, a facial recognition authentication method.
A multi-function sleep/wake button is located on the top of the device. It serves as the unit’s power button, and also controlsÂ phone calls. When a call is received, pressing the sleep/wake button once silences the ringtone, and when pressed twice transfers the call to voicemail. Situated on the left spine are the volume adjustment controls. The iPhone 4 has two separate circular buttons to increase and decrease the volume; all earlier models house two switches under a single plastic panel, known as a rocker switch, which could reasonably be counted as either one or two buttons.
Directly above the volume controls is a ring/silent switch that when engaged mutes telephone ringing, alert sounds from new & sent emails, text messages, and other push notifications, camera shutter sounds, Voice Memo sound effects, phone lock/unlock sounds, keyboard clicks, and spoken auto-corrections. This switch does not mute alarm sounds from the Clock application, and in some countries or regions it will not mute the camera shutter or Voice Memo sound effects.Â All buttons except Home were made of plastic on the original first-generation iPhone and metal on all later models. The touchscreen furnishes the remainder of theÂ user interface.
A software update in January 2008Â allowed the first-generation iPhone to use cell tower and Wi-Fi network locationsÂ trilateration,Â despite lackingÂ GPSÂ hardware. Since the iPhone 3G generation, the iPhone employsÂ A-GPSÂ operated by the United States. Since the iPhone 4S generation the device also supports theÂ GLONASSÂ global positioning system, which is operated by Russia. Since the iPhone 8 it supportsÂ Galileo.
The iPhone 6S and 6S Plus, introduced in 2015, featureÂ 3D TouchÂ displays which allow the screen to recognize how hard it is being pressed using pressure-sensitive multi-touch technology.Â An example of how this technology was used is lightly pressing the screen to preview a photograph and pressing down to take it. All subsequent iPhones with the exception of the first-generation iPhone SE and iPhone XRÂ had this feature until 2019. 3D Touch was omitted on the iPhone 11 and iPhone 11 Pro / 11 Pro Max in favor of Haptic Touch, which was previously featured on the iPhone XR. Haptic touch retains some of 3D Touch’s features but cannot detect pressure, as the display lacks integrated capacitive sensors.
iPhones feature a number of sensors, which are used to adjust the screen based on operating conditions, enable motion-controlled games,Â location-based services, unlock the phone, and authenticate purchases withÂ Apple Pay, among many other things.
AÂ proximity sensorÂ deactivates the display andÂ touchscreenÂ when the device is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs from the user’s face and ears.
Ambient light sensor
A 3-axisÂ accelerometerÂ senses the orientation of the phone and changes the screen accordingly, allowing the user to easily switch betweenÂ portrait and landscapeÂ mode.Â Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations.Â Unlike theÂ iPad, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen, unless the running program has been specifically designed to do so. The 3.0 update added landscape support for still other applications, such as email, and introduced shaking the unit as a form of input (generally forÂ undoÂ functionality).Â The accelerometer can also be used to controlÂ third-party apps, notably games. It is also used for fitness tracking purposes, primarily as aÂ pedometer. Starting with the iPhone 5S, this functionality was included in the M7Â Motion coprocessorÂ and subsequent revisions of the embedded chip.
AÂ magnetometerÂ is built-in since the iPhone 3GS, which is used to measure the strength and direction of the magnetic field in the vicinity of the device. Sometimes certain devices or radio signals can interfere with the magnetometer requiring users to either move away from the interference or re-calibrate by moving the device in a figure-eight motion. Since the iPhone 3GS, the iPhone also features a Compass app, which was unique at time of release, showing a compass that points in the direction of the magnetic field.
Some previous iPhone models contained a chip capable of receivingÂ radio signals;Â however, Apple has the FM radio feature switched off because there was no antenna connected to the chip. Later iterations of the iPhone (starting with the iPhone 7), however, do not contain radio chips at all.Â A campaign called “Free Radio On My Phone” was started to encourage cellphone manufacturers such as Apple to enable the radio on the phones they manufacture, reasons cited were that radio drains less power and is useful in an emergency such as theÂ 2016 Fort McMurray Wildfire.
Until 2017, iPhone models starting fromÂ iPhone 5SÂ (excluding theÂ iPhone 5C) featured Apple’sÂ fingerprint recognitionÂ sensor. It is used for unlocking the device and authenticating Apple Pay purchases (since theÂ iPhone 6) usingÂ Touch ID. It is located in the home button. Touch ID has been replaced by Face ID (excluding theÂ iPhone SE (2nd generation)), starting with theÂ iPhone X.
Facial recognition sensor
Starting with theÂ iPhone X, aÂ facial recognitionÂ sensor, named the TrueDepth camera system is featured. It is used for unlocking the device and for authenticating purchases usingÂ Face ID. It can also be used forÂ AnimojisÂ andÂ AR.
Audio and output
On the bottom of the iPhone, there is a speaker to the left of the dock connector and a microphone to the right. There is an additional loudspeaker above the screen that serves as an earpiece during phone calls. The iPhone 4 includes an additionalÂ microphoneÂ at the top of the unit forÂ noise cancellation, and switches the placement of the microphone and speaker on the base on the unitâ€”the speaker is on the right.Â Volume controls are located on the left side of all iPhone models and as a slider in the iPod application.
The 3.5Â mmÂ TRRS connectorÂ for the headphones is located on the top left corner of the device for the first five generations (original through 4S), after which time it was moved to the bottom left corner.Â The headphone socket on the first-generation iPhone is recessed into the casing, making it incompatible with most headsets without the use of an adapter.Â Subsequent generations eliminated the problem by using a flush-mounted headphone socket. Cars equipped with anÂ auxiliary jackÂ allow handsfree use of the iPhone while driving as a substitute forÂ Bluetooth. The iPhone 7 and later have no 3.5Â mm headphone jack,Â and instead headsets must connect to the iPhone byÂ Bluetooth, use Apple’sÂ Lightning portÂ (which has replaced the 3.5Â mm headphone jack), or (for traditional headsets) use the Lightning to 3.5Â mm headphone jack adapter, which is included with iPhone 7 up until iPhone X and plugs into the Lightning port.
Apple’s ownÂ headsetÂ has a multipurpose button near the microphone that can play or pause music, skip tracks, and answer or end phone calls without touching the iPhone. Some third-party headsets designed for the iPhone also include the microphone and control button.Â The current headsets also provide volume controls, which are only compatible with more recent models.Â A fourth ring in the audio jack carries this extra information.
The built-inÂ Bluetooth 2.x+EDRÂ supports wireless earpieces and headphones, which requires theÂ HSPÂ profile. Stereo audio was added in the 3.0 update for hardware that supportsÂ A2DP.Â While non-sanctioned third-party solutions exist, the iPhone does not officially support theÂ OBEXÂ file transferÂ protocol.Â The lack of these profiles prevents iPhone users from exchanging multimedia files, such as pictures, music and videos, with other Bluetooth-enabled cell phones.
CompositeÂ or componentÂ video at up toÂ 576iÂ and stereo audio can be output from the dock connector using an adapter sold by Apple. iPhone 4 also supports 1024Ã—768Â VGAÂ outputÂ without audio, andÂ HDMIÂ output,Â with stereo audio, via dock adapters. The iPhone did not supportÂ voice recordingÂ until the 3.0 software update.
The iPhone features an internal rechargeableÂ lithium-ion battery. Like an iPod, but unlike most other mobile phones at the time of its launch, the battery is not user-replaceable.Â The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar toÂ charging an iPod. Alternatively, a USB to AC adapter (or “wall charger”, also included) can be connected to the cable to charge directly from anÂ AC outlet. Some models of the iPhone support wireless charging.
Apple runs tests on preproduction units to determine battery life. Apple’s website says that the battery life “is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles”,Â which is comparable to iPod batteries.
The battery life of early models of the iPhone has been criticized by several technology journalists as insufficient and less than Apple’s claims.Â This is also reflected by aÂ J. D. Power and AssociatesÂ customer satisfaction survey, which gave the “battery aspects” of the iPhone 3G its lowest rating of two out of five stars.
If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still underÂ warranty.Â The warranty lasts one year from purchase and can be extended to two years withÂ AppleCare. The battery replacement service and its pricing was not made known to buyers until the day the product was launched;Â it is similar to how Apple (and third parties) replace batteries for iPods. TheÂ Foundation for Taxpayer and Consumer Rights, aÂ consumer advocateÂ group, has sent a complaint to Apple andÂ AT&TÂ over the fee that consumers have to pay to have the battery replaced.
SinceÂ iOS 10.2.1, Apple has instituted aÂ policyÂ of employing “performance management” techniques (includingÂ CPU throttling) on iPhone devices whose batteries are degraded, in order to maintain device stability and prolong their lifespan. These changes came in the wake of reported issues with unexpected shutdowns on certain iPhone models following the release of iOS 10.1.1. In response to criticism over the practice, including concerns over this being a form ofÂ planned obsolescence, Apple announced that it would offer discounted battery replacements for iPhone 6 and newer in 2018, and that it would add additional battery health information on a future version of iOS (iOS 11.3, which also allows users to disable this throttling).
Since July 2007, third-party battery replacement kits have been availableÂ at a much lower price than Apple’s own battery replacement program. These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the first generation iPhone has beenÂ solderedÂ in. Therefore, a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector that is easier to replace.Â The iPhone X features a different battery, with two battery cells, and the adhesive pull tabs are adhered to the sides instead of folded over the top, therefore making repairs a little more difficult than before.
A patent filed by the corporation, published in late July 2013, revealed the development of a new iPhone battery system that uses location data in combination with data on the user’s habits to moderate the handsets’ power settings accordingly. Apple is working towards a power management system that will provide features such as the ability to estimate the length of time a user will be away from a power source to modify energy usage and a detection function that adjusts the charging rate to best suit the type of power source that is being used.
The first-generation iPhone and iPhone 3G have aÂ fixed-focusÂ 2.0-megapixelÂ camera on the back for digital photos. It has no optical zoom, flash orÂ autofocus, and does not natively support video recording. Video recording is possible on the first-generation iPhone and iPhone 3G via a third-party app available on the App Store or throughÂ jailbreaking. iPhone OS 2.0 introducedÂ geotaggingÂ for photos.
The iPhone 3GS has a 3.2-megapixel camera with autofocus, auto white balance, and auto macro (up to 10Â cm). Manufactured byÂ OmniVision, the camera can also capture 640Ã—480 (VGAÂ resolution) video at 30 frames per second.Â The video can beÂ croppedÂ on the iPhone and directly uploaded toÂ YouTubeÂ or other services.
The iPhone 4 introduced a 5.0-megapixelÂ camera (2592Ã—1936 pixels) that can record video atÂ 720pÂ resolution, consideredÂ high-definition. It also has aÂ backside-illuminatedÂ sensor that can capture pictures in low light and anÂ LEDÂ flashÂ that can stay lit while recording video.Â It is the first iPhone that can natively doÂ high dynamic range photography.Â The iPhone 4 also has a second camera on the front that can takeÂ VGAÂ photos and recordÂ SDÂ video. Saved recordings may be synced to the host computer, attached to email, or (where supported) sent byÂ MMS.
The iPhone 4S’ camera can shoot 8-MP stills and 1080p video can be accessed directly from the lock screen and can be triggered using the volume-up button as a shutter trigger. The built-in gyroscope can stabilize the image while recording video.
The camera on theÂ iPhone 5Â reportedly shows purple haze when the light source is just out of frame,Â although Consumer Reports said it “is no more prone to purple hazing on photos shot into a bright light source than its predecessor or than several Android phones with fine cameras…”
On all five model generations, the phone can be configured to bring up the camera app by quickly pressing the home key twice.Â On all iPhones runningÂ iOS 5, it can also be accessed from the lock screen directly.
The iPhone 5S features True Tone Flash, which has two LED lights, white and amber, that will improve white balance and will be adjusted in 1,000 combinations. Its image sensor is now 15 percent larger than its previous model. The iPhone 5C, however, has the same camera features as the iPhone 5.
The iPhone 6S and 6S Plus are outfitted with a 12-megapixel camera, withÂ 4KÂ video capability at 30fps. The front-facing camera is upgraded to 5 megapixels. Other features added are Live Photos and Retina Flash, which turns the screen into a giant flash.Â Â The user may change the resolution between 4K and 1080p in Settings.
The first-generation iPhone SE features the same 12 MP camera found on the iPhone 6S and iPhone 6S Plus models, with the same 4K video capability, but its front camera only has 1.2 MP.
The iPhone 7 features optical image stabilization on its rear camera, a feature that was previously exclusive to the Plus models, and the 7 Plus is the first iPhone to feature dual-lens cameras (both 12 MP). Both models have a 7 MP front-facing camera. The second camera on the iPhone 7 Plus is aÂ telephoto lens, which enables 2Ã— optical zoom and up to 10Ã— digital zoom. The rear cameras on the 7 and 7 Plus both have an f/1.8Â aperture.Â It also has a new quad-LED True Tone flash, which is brighter compared to its predecessors.
The iPhone 8 camera remains largely the same as its predecessor, but it features a larger sensor and a newer color filter. The camera can also now recordÂ 4KÂ at 60 and 24 frames per second, andÂ slow-moÂ atÂ 1080pÂ in 240 frames per second. The new camera system also enables Portrait Lighting, which defines the light in a scene. It also features a quad-LED True Tone flash with 2Ã— better light uniformity and Slow Sync.
The iPhone X camera is almost the same as the iPhone 8’s camera, but theÂ telephotoÂ lens has anÂ apertureÂ of f/2.4 and optical image stabilization.Â The front camera also has Portrait Mode and Portrait Lighting, due to the new TrueDepth camera system.
The iPhone XS, XS Max, and XR have an updated 12MP (1/2.55″) sensor size with a 1.4 Î¼m pixel size. The XS series has a telephoto lens, while the lower end XR has only one lens. It also features Smart HDR, using the power of A12 Bionic chip, along with the Neural Engine, machine learning, artificial intelligence, and some advancements to provide better photos with improved dynamic range.
The iPhone 11, 11 Pro and 11 Pro Max introduced anÂ ultrawideÂ lens; the latter two became the first triple-camera iPhones. The 11 has a dual-lens setup, lacking the telephoto lens of the 11 Pro and 11 Pro Max. The front camera is now capable of recording video at 4K as a result of a new 12 MP sensor, and can also capture slow-motion footage.
The second-generation iPhone SE’s camera hardware is the same as the iPhone 8, but adds Portrait mode, Portrait lighting, Smart HDR, extended dynamic range for video up to 30 fps, stereo recording and cinematic video stabilization.
The iPhone was initially released with two options for internal storage size: 4 or 8Â GB. On September 5, 2007, Apple discontinued the 4Â GB models.Â On February 5, 2008, Apple added a 16Â GB model.
The iPhone 3G was available in 8 and 16Â GB when it was released in 2008.
The iPhone 3GS came in 16 and 32Â GB variants and remained available in 8Â GB until September 2012, more than three years after its launch.
The iPhone 4 was available in 16 and 32Â GB variants, as well as an 8Â GB variant, to be sold alongside the iPhone 4S at a reduced price point.Â The iPhone 4S was available in three sizes: 16, 32, and 64Â GB.
The iPhone 5 and 5S were available in the same three sizes as the iPhone 4S: 16, 32, and 64Â GB.Â The lower-cost iPhone 5C model was initially available in 16 and 32Â GB models; an 8Â GB model was added later.
When the iPhone 7 and 7 Plus were released, Apple changed the base model storage capacity from 16 to 32Â GB. Both the iPhone 7 and 7 Plus have configurations of 32, 128, and 256Â GB storage.Â Apple doubled the storage on the iPhone 6S and 6S Plus in two configurations[when?]Â (32 and 128Â GB), as well as the first-generation iPhone SE six months later.
The iPhone 8, 8 Plus, and X have changed their base model capacity again to 64GB while retaining the 256GB storage option.Â In 2019, the 256GB storage option on the iPhone 8 and 8 Plus was discontinued and replaced by a 128GB option.
The iPhone XS and iPhone XS Max introduced a 512GB storage option, in addition to the existing 64 and 256GB options. The iPhone XR comes in three storage options: 64, 128, and 256GB. The 256GB model on the iPhone XR was discontinued in 2019 and remained with two remaining storage options.
The iPhone 11 Pro and iPhone 11 Pro Max is available in the same three storage options as the iPhone XS and iPhone XS Max: 64, 256, and 512GB storage options. The iPhone 11 comes with the same storage options as the iPhone XR: 64, 128, and 256 GB.
The second-generation iPhone SE is available in the same storage options as the iPhone XR and iPhone 11: 64, 128 and 256GB configurations.
GSMÂ models of the iPhone use aÂ SIM cardÂ to identify themselves to the GSM network. The SIM sits in a tray, which is inserted into a slot at the top of the device. The SIM tray can be ejected with aÂ paper clipÂ or the “SIM ejector tool” (a simple piece of die-cut sheet metal) included with the iPhone 3G and 3GS in the United States and with all models elsewhere in the world.Â Some iPhone models shipped with a SIM ejector tool which was fabricated from an alloy dubbed “Liquidmetal“.Â In most countries, the iPhone is usually sold with aÂ SIM lock, which prevents the iPhone from being used on a different mobile network.
TheÂ CDMAÂ model of the iPhone 4, just the same as any other CDMA-only cell phone, does not use a SIM card or have a SIM card slot.
An iPhone 4S activated on a CDMA carrier, however, does have a SIM card slot but does not rely on a SIM card for activation on that CDMA network. A CDMA-activated iPhone 4S usually has a carrier-approved roaming SIM preloaded in its SIM slot at the time of purchase that is used for roaming on certain carrier-approved international GSM networks only. The SIM slot is locked to only use the roaming SIM card provided by the CDMA carrier.
In the case of Verizon, for example, one can request that the SIM slot be unlocked for international use by calling their support number and requesting an international unlock if their account has been in good standing for the past 60 days.Â This method only unlocks the iPhone 4S for use on international carriers. An iPhone 4S that has been unlocked in this way will reject any non-international SIM cards (AT&T Mobility or T-Mobile USA, for example).
The iPhone 5 and later iPhones useÂ nano-SIMÂ in order to save space internally. The iPhone XS and later iPhones addedÂ eSIMÂ support in addition to nano-SIM, therefore they support Dual SIM functionality.
Liquid contact indicators
All iPhones (as well as many other devices by Apple) have a small disc at the bottom of the headphoneÂ jackÂ that changes from white to red on contact with water; the iPhone 3G and later models also have a similar indicator at the bottom of theÂ dock connector.Â Because Apple warranties do not cover water damage, employees examine the indicators before approvingÂ warranty repair or replacement. However, with the adoption of water resistance as a feature of the iPhone, this practice is no longer in use by Apple.
The iPhone’s indicators are more exposed than those in some mobile phones from other manufacturers, which carry them in a more protected location, such as beneath the battery behind a battery cover. These indicators can be triggered during routine use, by an owner’s sweat,Â steam in a bathroom, and other light environmental moisture.Â Criticism led Apple to change its water damage policy for iPhones and similar products, allowing customers to request further internal inspection of the phone to verify if internal liquid damage sensors were triggered.
AllÂ iPhone modelsÂ include written documentation, and aÂ dock connectorÂ toÂ USBÂ cable. The first generation and 3G iPhones also came with a cleaning cloth. The first generation iPhone includes a stereoÂ headsetÂ (earbudsÂ and a microphone) and a plastic dock to hold the unit upright while charging and syncing. The iPhoneÂ 3GÂ includes a similar headset plus a SIM eject tool (the first generation model requires aÂ paperclip). The iPhoneÂ 3GSÂ includes theÂ SIMÂ eject tool and a revised headset, which adds volume buttons (not functional with previous iPhone versions).
The iPhone 3G and 3GS are compatible with the same dock, sold separately, but not the first generation model’s dock.Â All versions include a USB power adapter, or “wall charger”, which allows the iPhone to charge from anÂ AC outlet. The iPhone 3G and iPhone 3GS sold in North America, Japan, Colombia, Ecuador, and PeruÂ include an ultracompact USB power adapter.
In September 2014, with the launch of theÂ iPhone 6, Apple announcedÂ Apple Pay, a mobile payment system. The feature, aimed to “revolutionize” the way users pay, uses anÂ NFCÂ chip,Â Touch IDÂ fingerprint scanner (Face IDÂ on iPhone X and later), Apple’sÂ WalletÂ app, and a dedicated “Secure Element” chip for encrypted payment information to make purchases at participating stores, both physical and online.
All iPhone models have a haptic engine to vibrate when a notification or alert, incoming call, etc. iPhone models before the iPhone 4S use an eccentric rotating mass motor. The iPhone 4S uses a linear resonant actuator vibrator, which usually uses less power and creates a quieter vibration.Â However, the iPhone 5, 5C, and 5S uses an eccentric rotating mass motor. It is unsure as to why Apple decided to switch back. However, the iPhone 6 and 6 Plus uses a linear resonant actuator vibrator.
iPhone 6S and after uses taptic engine for vibration and haptic feedback, which works similar to the eccentric rotating mass motor.
The iPhone runs anÂ operating systemÂ known asÂ iOSÂ (formerly iPhone OS).Â It is a variant of theÂ DarwinÂ operating system core found inÂ macOS. Also included is the “Core Animation” software component fromÂ Mac OS X v10.5Â Leopard. Together with the graphics hardware (and on the iPhone 3GS,Â OpenGL ESÂ 2.0), it is responsible for the interface’sÂ motion graphics. The iPhone comes with a set of bundled applications developed by Apple,Â and supports downloading third-party applications through theÂ App Store.
TheÂ interfaceÂ is based around the home screen, a graphical list of available applications. iPhone applications normally run one at a time. Starting with the iPhone 4, a primitive version of multitasking came into play. Users could double click the home button to select recently opened applications.Â However, the apps never ran in the background. Starting with iOS 7, though, apps can truly multitask, and each open application runs in the background when not in use, although most functionality is still available when making a call or listening to music. The home screen can be accessed by a hardware button below the screen on the iPhone 8 and earlier. iPhone X and later models, with the exception of the second-generation iPhone SE, instead use touch-based gestures.
The original iPhone contained the following apps: Messages (SMSÂ andÂ MMSÂ messaging), Calendar, Photos, Camera, YouTube, Stocks, Maps (Google Maps), Weather, Voice Memos, Notes, Clock, Calculator, Settings andÂ iTunes (store). TheÂ App StoreÂ was introduced in iPhone OS 2 for the original iPhone and iPhone 3G.Â CompassÂ was added in iPhone OS 3 for the iPhone 3GS. FaceTime and Game Center were added in iOS 4 and 4.1 respectively. In iOS 5, Reminders and Newsstand were added, and the iPod application was split into separate Music and Videos applications. iOS 6 added Passbook as well as a new version of Maps called Apple Maps that relies on data provided by TomTom as well as other sources, and YouTube no longer came as a pre-installed application starting from that version. iOS 7 introduced a modern flat design for the interface and added a motion-based parallax feature to give the device a quasi-3D effect. iOS 8 added Health app. iOS 9 replaced Newsstand and Passbook withÂ NewsÂ andÂ Wallet. iOS 10 introduced Home and dedicated a page on the home screen for the widgets. iOS 11 added Files. iOS 12 introduced Measure, an app that usesÂ ARÂ technology to measure objects and things. It is available on devices with anÂ A9Â chip or newer.
Docked at the base of the screen, four icons forÂ Phone,Â Mail,Â SafariÂ (Internet), and Music delineate the iPhone’s main purposes.Â On January 15, 2008, Apple released software update 1.1.3, allowing users to create “Web Clips”, home screen icons that resemble apps that open a user-defined page in Safari. After the update, iPhone users can rearrange and place icons (by holding down on any icon and moving it to the desired location once they start shaking) on up to nine other adjacent home screens, accessed by a horizontal swipe.
Users can also add and delete icons from the dock, which is the same on every home screen. The dock holds up to four icons and is located at the bottom section of the screen. Each home screen holds up to twenty icons for theÂ first-generation iPhone,Â 3G,Â 3GS,Â 4Â andÂ 4S; TheÂ iPhone 5,Â 5C,Â 5S, andÂ first-generation iPhone SEÂ hold up to twenty-four icons; while theÂ iPhone 6Â and later iPhone models support up to twenty-eight icons. Users can delete Web Clips and third-party applications at any time and may select only certain applications for transfer from iTunes. Apple’s default programs could only be removed since the iOS 10 update. The 3.0 update added a system-wide search, known asÂ Spotlight, to the left of the first home screen.
Almost all input is given through the touch screen, which understands complex gestures usingÂ multi-touch. The iPhone’sÂ interaction techniquesÂ enable the user to move the content up or down by a touch-drag motion of the finger. For example, zooming in and out of web pages and photos is done by placing two fingers on the screen and spreading them farther apart or bringing them closer together, a gesture known as “pinching“.
Scrolling through a long list or menu is achieved by sliding a finger over the display from bottom to top, or vice versa to go back. In either case, the list moves as if it is pasted on the outer surface of a wheel, slowly decelerating as if affected by friction. In this way, the interfaceÂ simulates the physicsÂ of a real object. Unlike previous scrollable views, in which the user pressed a “down” control to move the view “downwards”, on iOS the user pushesÂ upwards, as if moving a “plank of wood floating on the water”, creating the impression that the user is directly manipulating the content displayed on the screen.
OtherÂ user-centeredÂ interactiveÂ effects include horizontally sliding sub-selection, the vertically sliding keyboard and bookmarks menu, and widgets that turn around to allow settings to be configured on the other side. Menu bars are found at the top and bottom of the screen when necessary. Their options vary by program but always follow a consistent style motif. In menu hierarchies, a “back” button in the top-left corner of the screen displays the name of the parent folder.
The iPhone allows audioÂ conferencing, call holding, call merging,Â caller ID, and integration with other cellular network features and iPhone functions. For example, if music is playing when a call is received, the music fades out and fades back in when the call has ended.
TheÂ proximity sensorÂ shuts off the screen and touch-sensitive circuitry when the iPhone is brought close to the face, both to save battery and prevent unintentional touches. The iPhone does not supportÂ video callingÂ orÂ videoconferencingÂ on versions prior to the fourth generation, as there is only one camera on the opposite side of the screen.
The iPhone 4 supports video calling using either the front or back camera over Wi-Fi, a feature Apple callsÂ FaceTime.Â Voice control, introduced in the iPhone 3GS, allows users to say a contact’s name or number and the iPhone will dial it.Â The first two models only supportÂ voice dialingÂ through third-party applications.
The iPhone includes aÂ visual voicemailÂ (in some countries)Â feature allowing users to view a list of current voicemail messages on-screen without having to call into their voicemail. Unlike most other systems, messages can be listened to and deleted in a non-chronological order by choosing any message from an on-screen list.
A musicÂ ringtoneÂ feature was introduced in the United States on September 5, 2007. Users can create custom ringtones from songs purchased from the iTunes Store for a small additional fee. The ringtones can be three to 30 seconds long from any part of a song, can fade in and out, pause from half a second to five seconds when looped, orÂ loop continuously. All customizing can be done in iTunes,Â or with Apple’sÂ GarageBandÂ software 4.1.1 or later (available only onÂ Mac OS X)Â or third-party tools.
With the release ofÂ iOS 6, which was released on September 19, 2012, Apple added features that enable the user to have options to decline a phone call when a person is calling them. The user can reply with a message, or set a reminder to call them back at a later time.
The layout of the music library is similar to that of anÂ iPod. The iPhone can sort its media library by songs, artists, albums, videos,Â playlists,Â genres, composers,Â podcasts,Â audiobooks, andÂ compilations. Options are presented alphabetically, except in playlists, which retain their order fromÂ iTunes. The iPhone uses a large font that allows users plenty of room to touch their selection.
Users can rotate their device horizontally toÂ landscape modeÂ to accessÂ Cover Flow. Like on iTunes, this feature shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen. Alternatively, headset controls can be used to pause, play, skip, and repeat tracks. On the iPhone 3GS, the volume can be changed with the included Apple Earphones, and the Voice Control feature can be used to identify a track, play songs in a playlist or by a specific artist, or create aÂ Genius playlist.
The iPhone supportsÂ gapless playback.Â Like theÂ fifth-generation iPodsÂ introduced in 2005, the iPhone can playÂ digital video, allowing users to watch TV shows and movies inÂ widescreen. Double-tapping switches between widescreen andÂ fullscreenÂ video playback.
The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone. The feature originally required a Wi-Fi network, but since 2012, it can be used on a cellular data network.
The iPhone includes software that allows the user to upload, view, and email photos taken with theÂ camera. The user zooms in and out of photos by sliding two fingers further apart or closer together, much like Safari. The camera application also lets users view the camera roll, the pictures that have been taken with the iPhone’s camera. Those pictures are also available in the Photos application, along with any transferred fromÂ iPhotoÂ orÂ ApertureÂ on a Mac, orÂ PhotoshopÂ on a Windows PC.
Internet access is available when the iPhone is connected to a local areaÂ Wi-FiÂ or a wide areaÂ GSMÂ orÂ EDGEÂ network, both second-generation (2G) wireless data standards. The iPhone 3G introduced support for third-generationÂ UMTSÂ andÂ HSDPAÂ 3.6,Â the iPhone 4S introduced support forÂ HSUPAÂ networks (14.4Â Mbit/s), and support for HSDPA 7.2 was introduced in the iPhone 3GS.Â Networks accessible from iPhone models includeÂ 1xRTTÂ (represented by a 1Ã— on the status bar) andÂ GPRSÂ (shown as GPRS on the status bar),Â EDGEÂ (shown as a capital E on the status bar),Â UMTSÂ andÂ EV-DOÂ (shown as 3G), a faster version of UMTS and 4G (shown as a 4G symbol on the status bar), andÂ LTEÂ (shown as LTE on the status bar).Â 5G Evolution is now supported on AT&T in areas where implemented and stylized as a larger 5G and reduced size capital E.Â 5GE uses the 4×4Â MIMOÂ doubling the number of antennas, 256-QAM, and three-wayÂ carrier aggregation. TrueÂ 5GÂ has not been implemented into the iPhone as of 2019.
AT&T introducedÂ 3GÂ in July 2004,Â but as late as 2007,Â Steve JobsÂ stated that it was still not widespread enough in the US, and the chipsets not energy efficient enough, to be included in the iPhone.Â Support forÂ 802.1X, an authentication system commonly used by university and corporate Wi-Fi networks, was added in the 2.0 version update.
By default, the iPhone will ask to join newly discoveredÂ Wi-FiÂ networks and prompt for the password when required. Alternatively, it can join closed Wi-Fi networks manually.Â The iPhone will automatically choose the strongest network, connecting to Wi-Fi instead of EDGE when it is available.Â Similarly, the iPhone 3G and onwards preferÂ 3GÂ toÂ 2G, and Wi-Fi to either.
Wi-Fi,Â Bluetooth, and 3G (on the iPhone 3G onwards) can all be deactivated individually.Â Airplane modeÂ disables all wireless connections at once, overriding other preferences. However, once in Airplane mode, one can explicitly enable Wi-Fi and/or Bluetooth modes to join and continue to operate over one or both of those networks while the cellular network transceivers remain off.
Safari is the iPhone’s nativeÂ web browser, and it displays pages similar to its Mac and Windows counterparts. Web pages may be viewed in portrait or landscape mode and the device supports automatic zooming by pinching together or spreading apart fingertips on the screen, or by double-tapping text or images.Â Safari does not allow file downloads except for predefined extensions.
The iPhone does not supportÂ Flash, which was still popular when the iPhone was introduced.Â Consequently, theÂ UK’s Advertising Standards AuthorityÂ adjudicated that an advertisement claiming the iPhone could access “all parts of the internet” should be withdrawn in its current form, on grounds ofÂ false advertising. In aÂ rare public letterÂ in April 2010, Apple CEOÂ Steve JobsÂ outlined the reasoning behind the absence of Flash on the iPhone (andÂ iPad).Â The iPhone supportsÂ SVG,Â CSS,Â HTMLÂ Canvas, andÂ Bonjour.Â Google ChromeÂ was introduced to the iOS on June 26, 2012, and Opera mini is also available.
The Maps application can accessÂ Google MapsÂ in map,Â satellite, or hybrid form. It can also generate directions between two locations, while providing optional real-time traffic information. During the iPhone’s announcement, Jobs demonstrated this feature by searching for nearbyÂ StarbucksÂ locations and then placing aÂ prank callÂ to one with a single tap.Â Support for walking directions, public transit, andÂ street viewÂ was added in the version 2.2 software update, but no voice-guided navigation.
The iPhone 3GS and iPhone 4 can orient the map with its digital compass.Â Apple also developed a separate application to view YouTube videos on the iPhone, which streams videos after encoding them using theÂ H.264Â codec. Simple weather andÂ stock quotesÂ applications also tap into the Internet.
iPhone users can and do access the Internet frequently, and in a variety of places. According toÂ Google, in 2008, the iPhone generated 50 times more search requests than any other mobile handset.Â According toÂ Deutsche TelekomÂ CEO RenÃ© Obermann, “The averageÂ Internet usageÂ for an iPhone customer is more than 100Â megabytes. This is 30 times the use for our average contract-based consumer customers.”Â NielsenÂ found that 98% of iPhone users use data services, and 88% use the internet.Â In China, the iPhone 3G and iPhone 3GS were built and distributed without Wi-Fi.
With the introduction of the Verizon iPhone in January 2011, the issue of using the internet while on the phone was brought to the public’s attention. Under the two U.S. carriers, internet and phone could be used simultaneously on AT&T networks, whereas Verizon networks only support the use of each separately.
However, in 2014, Verizon announced that the iPhone 6 and 6 Plus would allow simultaneous voice and data over its LTE Network.Â T-Mobile and Sprint have enabled calls over Wi-Fi, with Verizon and AT&T soon doing the same.
For text input, the iPhone implements aÂ virtual keyboardÂ on the touchscreen. It has automaticÂ spell checkingÂ and correction,Â predictive wordÂ capabilities, and a dynamic dictionary that learns new words. The keyboard can predict what word the user is typing and complete it, and correct for the accidental pressing of keys near the presumed desired key.
The keys are somewhat larger and spaced farther apart when inÂ landscape mode, which is supported by only a limited number of applications. Touching a section of text for a brief time brings up aÂ magnifying glass, allowing users to place theÂ cursorÂ in the middle of existing text. The virtual keyboard can accommodate 21 languages, including character recognition for Chinese.
Alternative characters with accents (for example, letters from the alphabets of other languages) andÂ emojiÂ can be typed from the keyboard by pressing the letter for two seconds and selecting the alternative character from the popup.Â The 3.0 update brought support forÂ cut, copy, or pastingÂ text, as well as landscape keyboards in more applications.Â On iPhone 4S and above, Siri allows dictation.
Since iOS 8, third party keyboards, distributed through the App Store, are allowed. Previously, they were only available on jailbroken iPhones.
Email and text messages
The iPhone also features an email program that supportsÂ HTML email, which enables the user to embed photos in an email message.Â PDF,Â Word,Â Excel, andÂ PowerPointÂ attachments to mail messages can be viewed on the phone.Â Yahoo!Â offers a free push-email service for the iPhone.Â IMAPÂ (although notÂ Push-IMAP) andÂ POP3Â mail standards are also supported, includingÂ Microsoft ExchangeÂ andÂ Kerio Connect.
In the first versions of the iPhone firmware, this was accomplished by opening up IMAP on the Exchange server. Apple has also licensedÂ Microsoft ActiveSyncÂ and supports the platform (including push email) with the release of iPhone 2.0 firmware.Â The iPhone will sync email account settings over from Apple’s ownÂ MailÂ application,Â Microsoft Outlook, andÂ Microsoft Entourage, or it can be manually configured on the device itself. The email program can access almost any IMAP or POP3 account.
Text messages are presented chronologically in a mailbox format similar to Mail, which places all text from recipients together with replies. Text messages are displayed in speech bubbles (similar toÂ iChat) under each recipient’s name. The iPhone has built-in support for email message forwarding, drafts, and direct internal camera-to-email picture sending. Support for multi-recipient SMS was added in the 1.1.3 software update.Â Support forÂ MMSÂ was added in the 3.0 update, but not for the original first generation iPhoneÂ and not in the U.S. until September 25, 2009.
AtÂ WWDC 2007Â on June 11, 2007, Apple announced that the iPhone would supportÂ third-partyÂ web applications usingÂ AjaxÂ that share the look and feel of the iPhone interface.Â On October 17, 2007, Steve Jobs, in an open letter posted to Apple’s “Hot News”Â weblog, announced that aÂ software development kitÂ (SDK) would be made available to third-party developers in February 2008.Â The iPhone SDK was officially announced and released on March 6, 2008, at the Apple Town Hall facility.
It is a free download, with an Apple registration, that allows developers to develop native applications for the iPhone and iPod Touch, then test them in an “iPhone simulator”. However, loading an application onto a real device is only possible after paying anÂ Apple Developer ConnectionÂ membership fee. Developers are free to set any price for their applications to be distributed through theÂ App Store, of which they will receive a 70% share.
Developers can also opt to release the application for free and will not pay any costs to release or distribute the application beyond the membership fee. The App Store was launched with the release of iPhone OS 2.0, on July 11, 2008.Â The update was free for iPhone users; owners of older iPod Touches were required to pay US$10 for it.
Once a developer has submitted an application to the App Store, Apple holds firm control over its distribution. Apple can halt the distribution of applications it deems inappropriate, for example,Â I Am Rich, a US$1000 program that simply demonstrated the wealth of its user.Â Apple has been criticized for banning third-party applications that enable a functionality that Apple does not want the iPhone to have: In 2008, Apple rejectedÂ Podcaster, which allowed iPhone users to download podcasts directly to the iPhone claiming it duplicated the functionality of iTunes.Â Apple has since released a software update that grants this capability.
NetShare, another rejected app, would have enabled users toÂ tetherÂ their iPhone to a laptop or desktop, using its cellular network to load data for the computer.Â Many carriers of the iPhone later globally allowed tethering before Apple officially supported it with the upgrade to the iPhone OS 3.0, withÂ AT&T MobilityÂ being a relative latecomer in the United States.Â In most cases, the carrier charges extra for tethering an iPhone.
Before the SDK was released, third parties were permitted to design “Web Apps” that would run through Safari.Â Unsigned native applications are also available for “jailbroken” phones.Â The ability to install native applications onto the iPhone outside of the App Store is not supported by Apple, the stated reason being that such native applications could be broken by any software update, but Apple has stated it will not design software updates specifically to break native applications other than those that perform SIM unlocking.
The original iPhone has been described as “revolutionary”,Â a “game-changer” for the mobile phone industry,Â and has been credited with helping to make Apple one of the world’s most valuable publicly traded companies by 2011.Â Newer iterations have also received praise, such as being called “the best phone”.
Starting with the iPhone 4S, Apple added anÂ accessibilityÂ feature to optimize the function of the iPhone withÂ hearing aids.Â Apple released a program of Made for iPhone Hearing Aids.Â These hearing aids deliver a power-efficient, high-quality digital audio experience and allow the user to manage the hearing aid right from the iPhone. Made for iPhone hearing aids also featureÂ Live Listen. With Live Listen the iPhone acts as a remoteÂ microphoneÂ that sends sound to a Made for iPhone hearing aid. Live Listen can help the user hear a conversation in a noisy room or hear someone speaking across the room.
TheÂ Braille DisplaysÂ for the iOS program was announced by Apple coinciding with the release of the iPhone 3GS,Â iPadÂ andÂ iPod Touch (3rd Generation). This program added support for more than 50 Bluetooth wireless braille displays that work with iOS out of the box. The user only needs to pair the keyboard to the device to start using it to navigate the iOS device withÂ VoiceOverÂ without any additional software. iOS supportsÂ braille tablesÂ for more than 25 languages.
iPhone lets the user know when an alert is sent to it, in a variety of notice methods. It delivers bothÂ visualÂ andÂ vibrating alertsÂ for incoming phone andÂ FaceTimeÂ calls, new text messages, new and sent mail, and calendar events. Users can set anÂ LED light flashÂ for incoming calls and alerts or have incoming calls display a photo of the caller. Users can choose from different vibration patterns or even create their own.
The iPhone can enlarge text to make it moreÂ accessibleÂ for vision-impaired users,Â and can accommodate hearing-impaired users withÂ closed captioningÂ and externalÂ TTYÂ devices.Â The iPhone 3GS also features white on black mode,Â VoiceOverÂ (aÂ screen reader), and zooming for impaired vision, and mono audio forÂ limited hearingÂ in one ear.Â Apple regularly publishes Voluntary Product Accessibility Templates which explicitly state compliance with the U.S. regulation “Section 508“.
With the release of iOS 9 for all iPhones, users have the ability to choose between two different screen view options. The user can choose to have a standard view or zoomed view. When the iPhone is placed in a standard view setting, the icons are normal size and the text remains the same. With a zoomed view option, the icons on the screen and the text become slightly larger. This enables the user to have a more customized appearance and it can potentially help some users read the screen easier.
AssistiveTouch helps to adapt theÂ Multi-TouchÂ screen of an iOS device to a user’s unique physical needs. This can be of great assistance to those who have difficulty with some gestures, like pinch, one can make them accessible with just a tap of a finger. The user can create their own gestures and customize the layout of the AssistiveTouch menu. If the user has trouble pressing the Home button, it can be set so that it can be activated with an onscreen tap. Gestures, like rotate and shake, are available even when if the iOS device is mounted on aÂ wheelchair.
Guided Access helps people withÂ autismÂ or otherÂ attentionÂ andÂ sensory challengesÂ stay focused on the task (or app) at hand. With Guided Access, a parent, teacher, or therapist can limit an iOS device to stay on one app by disabling the Home button and limit the amount of time spent in an app. The user can restrict access to the keyboard or touch input on certain areas of the screen.
In 2019 Apple began developing satellites so that the iPhone could skip wireless carriers.
25 different iPhone models have been produced. The models inÂ boldÂ are current flagship devices:
LG Electronics claimed the design of the iPhone was copied from theÂ LG Prada. Woo-Young Kwak, head of LG Mobile Handset R&D Center, said at a press conference: “we consider that Apple copied Prada phone after the design was unveiled when it was presented in the iF Design Award and won the prize in September 2006.”Â Conversely, the iPhone has also inspired its own share of high-tech clones.
On September 3, 1993,Â InfogearÂ filed for the U.S. trademark “I PHONE”Â and on March 20, 1996, applied for the trademark “IPhone”.Â “I Phone” was registered in March 1998,Â and “IPhone” was registered in 1999.Â Since then, the I PHONE mark had been abandoned.Â Infogear trademarks cover “communications terminals comprising computer hardware and software providing integrated telephone, data communications and personal computer functions” (1993 filing),Â and “computer hardware and software for providing integrated telephone communication with computerized global information networks” (1996 filing).
In 2000, Infogear filed an infringement claim against the owners of the iPhones.com domain name.Â The owners of the iPhones.com domain name challenged the infringement claim in the Northern District Court of California. In June 2000, Cisco Systems acquired Infogear, including theÂ iPhoneÂ trademark.Â In September 2000, Cisco Systems settled with the owners of iPhones.com and allowed the owners to keep the iPhones.com domain name along with intellectual property rights to use any designation of the iPhones.com domain name for the sale of cellular phones, cellular phones with Internet access (WAP PHONES), handheld PDAs, storage devices, computer equipment (hardware/software), and digital cameras (hardware/software). The intellectual property rights were granted to the owners of the iPhones.com domain name by Cisco Systems in September 2000.
In October 2002, Apple applied for the “iPhone” trademark in the United Kingdom, Australia, Singapore, and the European Union. A Canadian application followed in October 2004, and a New Zealand application in September 2006. As of October 2006, only the Singapore and Australian applications had been granted.
In September 2006, a company called Ocean Telecom Services applied for an “iPhone” trademark in the United States, United Kingdom, and Hong Kong, following a filing in Trinidad and Tobago.Â As the Ocean Telecom trademark applications use exactly the same wording as the New Zealand application of Apple, it is assumed that Ocean Telecom is applying on behalf of Apple.Â The Canadian application was opposed in August 2005, by a Canadian company calledÂ ComwaveÂ who themselves applied for the trademark three months later. Comwave has been selling VoIP devices called iPhone since 2004.
Shortly after Steve Jobs’ January 9, 2007 announcement that Apple would be selling a product called iPhone in June 2007, Cisco issued a statement that it had been negotiating trademark licensing with Apple and expected Apple to agree to the final documents that had been submitted the night before.Â On January 10, 2007, Cisco announced it had filed a lawsuit against Apple over the infringement of the trademark iPhone, seeking an injunction in federal court to prohibit Apple from using the name.Â In February 2007, Cisco claimed that the trademark lawsuit was a “minor skirmish” that was not about money, but about interoperability.
On February 2, 2007, Apple and Cisco announced that they had agreed to temporarily suspend litigation while they held settlement talks,Â and subsequently announced on February 20, 2007, that they had reached an agreement. Both companies will be allowed to use the “iPhone” nameÂ in exchange for “exploring interoperability” between their security, consumer, and business communications products.
On October 22, 2009,Â NokiaÂ filed a lawsuit against Apple for infringement of its GSM, UMTS and WLAN patents. Nokia alleges that Apple has been violating ten Nokia patents since the iPhone initial release.
In December 2010,Â ReutersÂ reported that some iPhone andÂ iPadÂ users were suingÂ Apple Inc.Â because some applications were passing user information to third-party advertisers without permission. Some makers of the applications such as Textplus4,Â Paper Toss,Â The Weather Channel,Â Dictionary.com, Talking Tom Cat and Pumpkin Maker have also been named as co-defendants in the lawsuit.
In August 2012, Apple won aÂ smartphone patent lawsuitÂ in the U.S. againstÂ Samsung, the world’s largest maker of smartphones;Â however, on December 6, 2016,Â SCOTUSÂ reversed the decision that awarded nearly $400 million to Apple and returned the case to Federal Circuit court to define the appropriate legal standard to define “article of manufacture” because it is not the smartphone itself but could be just the case and screen to which the design patents relate.
In March 2013, an Apple patent for a wraparound display was revealed.
Location tracking controversies
Around April 20, 2011, aÂ hiddenÂ unencryptedÂ file on the iPhone and other iOS devices was widely discussed in the media.Â It was alleged that the file, labeled “consolidated.db”, constantly stores the iPhone user’s movement by approximating geographic locations calculated byÂ triangulating nearby cell phone towers, a technology proven to be inaccurate at times.Â The file was released with the June 2010 update of AppleÂ iOS4Â and may contain almost a year’s worth of data. Previous versions of iOS stored similar information in a file called “h-cells.plist”.
F-SecureÂ discovered that the data is transmitted to Apple twice a day and postulate that Apple is using the information to construct their global location database similar to the ones constructed by Google andÂ SkyhookÂ throughÂ wardriving.Â Nevertheless, unlike theÂ GoogleÂ “Latitude” application, which performs a similar task onÂ AndroidÂ phones, the file is not dependent upon signing a specificÂ EULAÂ or even the user’s knowledge, but it is stated in the 15,200 word-longÂ terms and conditionsÂ of the iPhone that “Apple and [their] partners and licensees may collect, use, and share precise location data, including the real-time geographic location of [the user’s] Apple computer or device”.
The file is also automatically copied onto the user’s computer once synchronized with the iPhone. AnÂ open-source applicationÂ named “iPhoneTracker”, which turns the data stored in the file into a visual map, was made available to the public in April 2011.Â While the file cannot be erased withoutÂ jailbreakingÂ the phone, it can be encrypted.
Apple gave an official response on their web site on April 27, 2011,Â after questions were submitted by users, theÂ Associated PressÂ and others. Apple clarified that the data is a small portion of their crowd-sourced location database cache of Wi-Fi hotspots and cell towers which is downloaded from Apple into the iPhone for making location services faster than with only GPS, therefore the data does not represent the locations of the iPhone. The volume of data retained was an error. Apple issued an update for iOS (versionÂ 4.3.3, orÂ 4.2.8Â for the CDMA iPhone 4) which reduced the size of the cache, stopped it being backed up to iTunes, and erased it entirely whenever location services were turned off.Â The upload to Apple can also be selectively disabled from “System services”, “Cell Network Search.” Regardless, in July 2014, a report on state-owned China Central Television labeled the iPhone a “national security concern.”
The “Frequent Locations” feature found in “Settings” under “Location Services” stores commonly visited locations locally on the device.Â This feature is said to help the accuracy of the GPS and Apple Maps since it can log information about the locations the user has frequently visited. However, this feature also keeps track of the number of times that the user has been to that location, the dates, and the exact times. Media outlets have publicized instructions on how this can be disabled for concerned users.
Encryption and intelligence agency access
It was revealed as a part of theÂ 2013 mass surveillance disclosuresÂ that the American and British intelligence agencies, theÂ National Security AgencyÂ (NSA) and theÂ Government Communications HeadquartersÂ (GCHQ) have access to the user data in iPhones, BlackBerrys, and Android phones, respectively. They can read almost all smartphone information, including SMS, location, emails, and notes.
According to an article inÂ The New York TimesÂ titled “Signaling Post-Snowden Era, New iPhone Locks Out N.S.A.”, Apple has developed a new encryption method for iOS 8, described as “so deep that Apple could no longer comply with government warrants asking for customer information to be extracted from devices.”
Throughout 2015, prosecutors in the United States argued for the U.S. government to be able to compel decryption of iPhone contents.Â After theÂ 2015 San Bernardino attack, theÂ FBIÂ recovered anÂ iPhone 5CÂ that was issued to one of the shooters by his employer, andÂ iCloudÂ backups of that phone from a month and a half before the shooting. (The shooters had destroyed their personal phones.) The U.S. government attempted to obtain a court order under theÂ All Writs ActÂ compelling Apple to produce anÂ IPSWÂ file that would allow investigators toÂ brute forceÂ the device passcode.Â Tim CookÂ responded on the company’s website, outlining a need for encryption, arguing that if they produce aÂ backdoorÂ for one device, it would inevitably be used to compromise the privacy of other iPhone users.Â On February 19, Apple communicated to journalists that the password for the Apple ID for the iPhone had been changed within a day of the government obtaining it, preventing Apple from producing a workaround that would only target older devices.Â SeeÂ FBIâ€“Apple encryption dispute.
Apple iOS in combination with their specific hardware usesÂ crypto-shreddingÂ when activating the “Erase all content and settings” byÂ obliteratingÂ all the keys in ‘effaceableÂ storage’. This renderes all user data on the device cryptographically inaccessible.
Apple tightly controls certain aspects of the iPhone. According toÂ Jonathan Zittrain, the emergence ofÂ closed devicesÂ like the iPhone have made computing moreÂ proprietaryÂ than early versions ofÂ Microsoft Windows.
TheÂ hackerÂ community has found many workarounds, most of which are disallowed by Apple and make it difficult or impossible to obtain warranty service.Â “Jailbreaking” allows users to install apps not available on the App Store or modify basic functionality. SIM unlocking allows the iPhone to be used on a different carrier’s network.Â However, in the United States, Apple cannot void an iPhone’s warranty unless it can show that a problem or component failure is linked to the installation or placement of an after-market item such as unauthorized applications, because of theÂ Federal Trade Commission‘sÂ Magnuson-Moss Warranty Act of 1975.
The iPhone normally prevents access to its media player and web features unless it has also been activated as a phone with an authorized carrier. On July 3, 2007,Â Jon Lech JohansenÂ reported on his blog that he had successfully bypassed this requirement and unlocked the iPhone’s other features with a combination of custom software and modification of the iTunes binary. He published the software and offsets for others to use.
Unlike the first generation iPhone, the iPhone 3G must be activated in the store in most countries.Â This makes the iPhone 3G more difficult, but not impossible, to hack. The need for in-store activation, as well as the huge number of first-generation iPhone andÂ iPod TouchÂ users upgrading to iPhone OS 2.0, caused a worldwideÂ overloadÂ of Apple’sÂ serversÂ on July 11, 2008, the day on which both the iPhone 3G and iPhone OS 2.0 updates as well asÂ MobileMeÂ were released. After the update, devices were required to connect to Apple’s servers to authenticate it, causing many devices to be temporarily unusable.
Users on theÂ O2Â network in the United Kingdom, however, can buy the phone online and activate it via iTunes as with the previous model.Â Even where not required, vendors usually offer activation for the buyer’s convenience. In the US, Apple has begun to offer free shipping on both the iPhone 3G and the iPhone 3GS (when available), reversing the in-store activation requirement.Â Best BuyÂ andÂ WalmartÂ will also sell the iPhone.
Unapproved third-party software and jailbreaking
The iPhone’s operating system is designed to only run software that has an Apple-approvedÂ cryptographic signature. This restriction can be overcome by “jailbreaking” the phone,Â which involves replacing the iPhone’sÂ firmwareÂ with a slightly modified version that does not enforce the signature check. Doing so may be a circumvention of Apple’sÂ technical protection measures.Â Apple, in a statement to theÂ United States Copyright OfficeÂ in response toÂ Electronic Frontier FoundationÂ (EFF) lobbying for a DMCA exception for this kind of hacking, claimed that jailbreaking the iPhone would beÂ copyright infringementÂ due to the necessary modification of system software.Â However, in 2010, Jailbreaking was declared officially legal in the United States by theÂ DMCA.Â Jailbroken iPhones may be susceptible to computer viruses, but few such incidents have been reported.
In 2007, 2010, and 2011, developers released a series of tools calledÂ JailbreakMeÂ that used security vulnerabilities in Mobile Safari rendering toÂ jailbreakÂ the device (which allows users to install any compatible software on the device instead of only App Store apps).Â Each of these exploits were quickly fixed by iOS updates from Apple. Theoretically these flaws could have also been used for malicious purposes.
In July 2011, Apple released iOS 4.3.5 (4.2.10 for CDMA iPhone) to fix a security vulnerability with certificate validation.
Following the release of the iPhone 5S model, a group of German hackers called theÂ Chaos Computer ClubÂ announced on September 21, 2013, that they had bypassed Apple’s new Touch ID fingerprint sensor by using “easy everyday means.” The group explained that the security system had been defeated by photographing a fingerprint from a glass surface and using that captured image as verification. The spokesman for the group stated: “We hope that this finally puts to rest the illusions people have about fingerprint biometrics. It is plain stupid to use something that you can’t change and that you leave everywhere every day as a security token.”
Most iPhones were and are stillÂ sold with aÂ SIM lock, which restricts the use of the phone to one particular carrier, a common practice with subsidizedÂ GSMÂ phones. Unlike most GSM phones, however, the phone cannot be officially unlocked by entering a code.Â The locked/unlocked state is maintained on Apple’s serversÂ perÂ IMEIÂ and is set when the iPhone is activated.[failed verification]
While the iPhone was initiallyÂ sold in the U.S. only on the AT&T networkÂ with a SIM lock in place, various hackers have found methods to “unlock” the phone from a specific network.Â Although AT&T, Sprint, T-Mobile and Verizon are the only authorized iPhone carriers in the United States, unlocked iPhones can be used with other carriers.Â For example, an unlocked iPhone may be used on the T-Mobile network in the U.S. but, while an unlocked iPhone is compatible with T-Mobile’sÂ voiceÂ network, it may not be able to make use of 3G or 4G functionality (i.e. no mobile web or e-mail, etc.).[failed verification]Â More than a quarter of the original first generation iPhones sold in the U.S. were not registered with AT&T. Apple speculates that they were likely shipped overseas and unlocked, a lucrative market before the iPhone 3G’s worldwide release.
On March 26, 2009, AT&T in the United States began selling the iPhone without a contract, though still SIM-locked to their network.Â The up-front purchase price of such iPhone units is often twice as expensive as those bundled with contracts.
Outside of the United States, policies differ, especially in U.S. territories and insular areas likeÂ Guam;Â GTA TeleguamÂ was the exclusive carrier for the iPhone since its introduction, as none of the four U.S. carriers (AT&T, Sprint, T-Mobile, and Verizon) have a presence in the area.Â Since 2013,Â Docomo PacificÂ ended GTA’s exclusivity starting with the iPhone 5.
Beginning April 8, 2012, AT&T began offering a factory SIM unlock option (which Apple calls a “whitelisting”, allowing it to be used on any carrier the phone supports) for iPhone owners.
It has been reported that all of the Verizon 4GÂ LTE phones come factory unlocked. After such discovery, Verizon announced that all of their 4GÂ LTE phones, including iPhones, would remain unlocked. This is due to the regulations that the FCC has placed on the 700Â MHz C-Block spectrum,Â which is used by Verizon.Â AppleÂ loses moreÂ moneyÂ than it makes on repair services in the US.
In the United Kingdom,Â O2,Â EE,Â 3,Â Vodafone, andÂ Tesco MobileÂ sell the device under subsidized contracts, or for use on a pay as you go. They are locked to the network initially, though they can usually be unlocked either after a certain period of contract length has passed, or for a small fee (with the exception of theÂ 3Â network, which will unlock the device at any time for no charge).Â However, all current versions of iPhone are available for purchaseÂ SIM-freeÂ from the Apple Store or Apple’s Online Store, consequently, they are unlocked for use on any GSM network too.
All iPhones purchased for full retail price at anÂ Apple StoreÂ or online at apple.com come unlocked which allows customer selection of carriers.
iPhones sold inÂ CanadaÂ purchased through mobile carries such asÂ TELUS,Â Rogers, orÂ BellÂ were locked to their respective networks and unlocking required visiting a carrier store and paying an unlocking fee. Third-party methods to unlock iPhones existed but were highly unreliable and sometimes rendered phones unusable.Â However, in 2017 theÂ CRTCÂ abolished SIM-locking and required that all mobile devices sold after December 1, 2017, come unlocked.Â TheÂ CRTCÂ also mandated that carriers must offer unlocking services of existing devices for free to consumers, regardless of whether or not they had purchased the phone themselves.
Australia and other countries
Internationally, policies vary, but many carriers sell the iPhone unlocked for full retail price.
Legal battles over brand name
In 2003, four years before the iPhone was officially introduced, the trademark iFone was registered inÂ MexicoÂ by a communications systems and services company, iFone.Â Apple tried to gain control over its brand name, but a Mexican court denied the request. The case began in 2009, when the Mexican firm sued Apple. TheÂ Supreme Court of MexicoÂ upheld that iFone is the rightful owner and held that Apple iPhone is a trademark violation.
In Brazil, the brand IPHONE was registered in 2000 by the company then called Gradiente EletrÃ´nica S.A., now IGB EletrÃ´nica S.A. According to the filing, Gradiente foresaw the revolution in the convergence of voice and data over the Internet at the time.
In Brazil, the final battle over the brand name concluded in 2008. On December 18, 2012, IGB launched its own line of Android smartphones under the tradename to which it has exclusive rights in the local market.Â In February 2013, the Brazilian Patent and Trademark Office (known as “Instituto Nacional da Propriedade Industrial”) issued a ruling that Gradiente EletrÃ´nica, not Apple, owned the “iPhone” mark in Brazil. The “iPhone” term was registered by Gradiente in 2000, 7 years before Apple’s release of its first iPhone. This decision came three months after Gradiente EletrÃ´nica launched a lower-cost smartphone using the iPhone brand.
In June 2014, Apple won, for the second time, the right to use the brand name in Brazil. The court ruling determined that the Gradiente’s registration does not own exclusive rights on the brand. Although Gradiente intended to appeal, with the decision Apple can use freely the brand without paying royalties to the Brazilian company.
In theÂ Philippines, Solid Group launched theÂ MyPhoneÂ brand in 2007. Stylized as “my|phone”, Solid Broadband filed a trademark application of that brand. Apple later filed a trademark case at the Intellectual Property Office of the Philippines (IPOPHL) against Solid Broadband’s MyPhone for “confusingly similar” to the iPhone and that it may likely “deceive” or “cause confusion” among consumers.
Apple lost the trademark battle to Solid Group in a 2015 decision made by IPO director Nathaniel Arevalo, who also reportedly said that it was unlikely that consumers would be confused between the “iPhone” and the “MyPhone”. “This is a case of a giant trying to claim more territory than what it is entitled to, to the great prejudice of a local ‘Pinoy Phone’ merchant who has managed to obtain a significant foothold in the mobile phone market through the marketing and sale of innovative products under a very distinctive trademark”, Arevalo later added.
