iPhone 3G features a continuous sculpted polycarbonate back that feels even better in your hand. A stainless steel band surrounds the gorgeous optical-quality glass with superior clarity and scratch resistance. The 3.5" multi-touch display allows users to control iPhone with just a tap, flick or pinch of their fingers. Changes to volume, muting the ringer and putting an incoming call through to voicemail can be done using discreet stainless steel buttons on the top and side of iPhone. iPhone 3G comes in white or black. iPhone 3G combines all the revolutionary features of iPhone with 3G networking that is twice as fast as the first generation.
