iPhone 3G teardown
The iPhone 3G has substantial differences within its hardware beyond 3G and GPS chips, one of the first teardowns shows. A model obtained early from New Zealand reveals, for example, that unlike the first iPhone, the glass and LCD in the display are separate, mimicking the construction of the iPod touch. The display assembly is also no longer used to anchor miscellaneous components, but rather just the main board.
Apple has merged the logic and communications boards together instead of stacking them, and perhaps critically for repair teams and home upgraders, the battery is no longer soldered, making it easier to remove. Chips so far remain mostly unidentified, but the phone does use Intel NOR flash and Skyworks power management.
