The iPhone (colloquially known, retronymically, as the iPhone 2G, the first iPhone, and iPhone 1 after 2008 to differentiate it from later models) is the first smartphone designed and marketed by Apple Inc. After years of rumors and speculation, it was officially announced on January 9, 2007, and was later released in the United States on June 29, 2007. It featured quad-band GSM cellular connectivity with GPRS and EDGE support for data transfer.
Development of the iPhone dated back to 2005, when former Apple CEO Steve Jobs conceived the idea. The design was expanded upon over the next 2 years in complete secrecy, before being announced in 2007.
Although several aspects of the iPhone are considered obsolete by current standards, the device is seen as a prototype for current cell phones, eliminating most physical hardware buttons and stylus in favor of a touch-based user interface. Its successor, the iPhone 3G, was announced in June 2008.
