- This article is about Apple's line of smartphones. For the first iPhone see: iPhone (1st generation).
The iPhone is a line of high end smartphones, designed and marketed by Apple Inc. The first iPhone was unveiled by Steve Jobs, then CEO of Apple, on January 9, 2007, and released on June 29, 2007. The 15th generation models, the iPhone 13, 13 mini, 13 Pro, and 13 Pro Max, were announced on September 14, 2021, while the 3rd-generation iPhone SE, was announced on March 8, 2022, and include iOS 15, Apple's latest operating system for handheld devices.
All iPhones can function as a video camera (since the the iPhone 3GS), a camera phone, a portable media player, and an internet client with email and web browsing capabilities, can send texts and receive visual voicemail, and has both Wi-Fi through 4G connectivity (the original iPhone only supported EDGE/2G). The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. Third-party as well as Apple application software is available from the App Store, which launched in mid-2008 and now has over 900,000 "apps" approved by Apple. These apps have diverse functions, including games, reference, GPS navigation, social networking, security and advertising for television shows, films, and celebrities.
Since 1982, Hartmut Esslinger and other designers at Apple Computer had been experimenting with various concepts incorporating telephone features before the advent of smartphones, though none of these ever reached the market. There were some 3rd party products based on Apple's Newton platform, such as the Siemens NotePhone and Digital Ocean Seahorse, that were released in 1993 and 1996, respectively.
With the increasing popularity of Apple's new iPod line in 2002, CEO Steve Jobs expressed concern about other product categories that may cannibalize its potential, such as mobile phones. Though publicly denying it, Apple began work on a touch-sensitive tablet. Apple had been a longtime partner with Motorola for its processors and announced an agreement on July 26, 2004 to jointly develop an "iTunes phone" that would become the Motorola ROKR E1. Steve Sakoman, VP of OS and server technology who formerly headed the Newton project, was concerned about development for Motorola's phone and advocated to Jobs that Apple create its own. Jobs personally had low expectations of Motorola, but was concerned about the influence of mobile carriers at the time. In the meantime, Jobs was gathering information to eventually pursue a deal with Cingular Wireless (now AT&T Mobility). Michael Bell, VP of CPU software, stated that he sent Jobs an email in November 2004 also advocating for an Apple-developed phone. Scott Forstall, senior director at the time, said that Jobs was finally motivated after being annoyed by a Microsoft executive who claimed that their Windows tablet and stylus would "rule the world". Jobs then instructed Forstall to put the tablet on hold and redirect the effort towards the phone.
At least two operating system candidates entered into development in 2004 and many user interfaces were prototyped, ranging from Multi-touch to variations of the Click Wheel interface. Jon Rubinstein led development on a lightweight Linux-based version (referred to as "Acorn") while Avie Tevanian and Scott Forstall worked to create a streamlined version of Mac OS X (codenamed "Purple") to run on the ARM chipset. "Purple" was chosen in reference to other project codenames based on color. Forstall stated that only engineers from within the company were permitted to be recruited for the project. Secrecy was so guarded that they were not told what they would be working on. The team secured a building which was nicknamed the "Purple Dorm" with a Fight Club poster on the front door. UI concepts were mocked up in Macromedia Director before being ported to run on prototype ARM hardware. Though Tony Fadell communicated that the Linux-based version may be a waste of time, CEO Steve Jobs insisted on prototyping all options for evaluation. Two of the hardware prototypes that were assembled were identified as "P1" and "P2". P1 was based on the "Acorn OS" that used a software implementation of the Click Wheel on the touch screen; P2 used a simplified version of Mac OS X with touch-based buttons. Though the OS X version was limited and took longer to boot, it was selected for final development to become the first iPhone OS.
After Steve Jobs announced the first iPhone on January 9, 2007, he complained to VP of operations Jeff Williams about the scratches that had already developed on the plastic screen of the prototype and said, "We need glass." Two days later, Corning CEO Wendell Weeks contacted Williams to tell him: "Hey, your boss called and said my glass sucks." Apple and Corning then scrambled to develop a manufacturing process for a new type of chemically strengthened glass that Corning had been researching. By late June, the iPhones began shipping with the glass screens which later became known as Gorilla Glass.

Released on June 29, 2007 with much fanfare, the first iPhone was a GSM model that established design precedents like screen size and button placement that have persisted through many models, including the current iPhone SE.
The iPhone 4 featured a higher-resolution 960x640 Retina display, improved rear facing camera (720p video) and introduced a front facing camera (at a lower VGA resolution) for FaceTime video calling and for use in other apps like Skype.

The iPhone 4s added a higher resolution camera (8 megapixel) with 1080p video recording, face detection, video stabilization, a faster, dual core A5 processor, multi-standard wireless support (allowing a single handset to operate on networks based on both GSM/UMTS and CDMA technologies), GLONASS support, Bluetooth 4.0 and a natural language voice control system called Siri. It was available in 16 GB, 32 GB, and 64 GB capacity options. In the United States, it was announced that two carriers, C Spire and Sprint, would begin carrying the iPhone 4 and iPhone 4s on October and November 2011, respectively.

The XR utilized a slightly larger Liquid Retina display, which used a more conventional panel than OLED, but shaped to resemble the edge-to-edge display of the iPhone X, and single-lens camera to reduce its cost to customers. The iPhone XS used the same OLED panel as the iPhone X, but included a larger camera and upgraded the 2x2 MIMO antenna to 4x4, improving 4G bandwidth. The XS Max included these improvements with an even larger OLED display.
iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max
