The iPhone — retroactively labeled the original iPhone, iPhone 2G, or iPhone EDGE—was the first generation of iPhone designed and marketed by Apple Inc. and was succeeded by the iPhone 3G.
It was announced on January 9, 2007 after months of rumors and speculation. It was introduced in the United States on June 29, 2007 before being marketed in Europe. It featured quad-band GSM with GPRS and EDGE.
The original iPhone no longer receives software updates from Apple; its final firmware version was iOS 3.1.3.
