⭐ Core Definition: IPhone (1st generation)

The iPhone (also known as the iPhone 1st generation or iPhone 2G) is a smartphone developed and marketed by Apple as the first device in the iPhone lineup of smartphones. It features a Samsung S5L8900 SoC (90 nm), a 3.5 in multi-touch display, and a web browser (Safari). After years of rumors and speculation, it was officially announced on January 9, 2007, and was released in the United States on June 29, 2007.

Development of the iPhone began in 2005 and continued in secrecy until its public unveiling at Macworld 2007. The device broke with prevailing mobile phone designs by eliminating most physical hardware buttons, and relying on a finger-friendly touchscreen interface that did not need a stylus. The iPhone featured quad-band GSM cellular connectivity with GPRS and EDGE support for data transfer, and it used continuous internet access and onboard processing to support features unrelated to voice communication.

IPhone (1st generation) in the context of IPhone

The iPhone is a line of smartphones developed and marketed by Apple that run iOS, the company's own mobile operating system. The first-generation iPhone was announced by then–Apple CEO and co-founder Steve Jobs on January 9, 2007, at Macworld 2007, and launched later that year. Since then, Apple has annually released new iPhone models and iOS versions; the latest models being the iPhone 17, the higher-end iPhone 17 Pro and 17 Pro Max, and the thinner iPhone Air. As of July 2025, more than 3 billion iPhones have been sold, and Apple has been the largest vendor of mobile phones since 2023.

The original iPhone was the first mobile phone to use multi-touch technology. Throughout its history, the iPhone has gained larger, higher-resolution displays, video-recording functionality, waterproofing, and many accessibility features. Up to the iPhone 8 and 8 Plus, iPhones had a single button on the front panel, with the iPhone 5s and later integrating a Touch ID fingerprint sensor. Since the iPhone X, iPhone models have switched to a nearly bezel-less front screen design with Face ID facial recognition in place of Touch ID for authentication, and increased use of gestures in place of the home button for navigation.
