Background and Identification
The iPhone 3G was the first iPhone to include 3G web surfing capabilities. The 8 GB iPhone 3G is completely black (front and back) with silver side buttons, while the 16 GB version offers a choice of black or white.
In terms of repairability, the iPhone 3G is not too bad. The display assembly comes off pretty easily with a suction cup and some plastic opening tools. The front glass can be replaced separately from the rest of the display assembly, saving money when replacing a shattered front panel. Since the phone is built from back to front, the rear panel is the hardest to replace and requires completely dismantling the entire device.
