Logic board much smaller than that of iPhone 3GS
The purported next-generation iPhone prototype has already been dissected to reveal its internal components. The images, posted on Gizmodo, show a housing that can be halved after removing two screws. The new battery appears to be larger than that of earlier iPhone models, filling nearly half the volume of the internal cavity.
Interestingly enough, the iPhone prototype integrates a logic board that is much smaller than the components used on the 3GS. Most of the individual chips were covered in additional metal protectors, however, which were not removed during the teardown.
Apple labels inside the device appear to corroborate suggestions that it is a genuine iPhone prototype, although it is still unclear if the leaked device represents the final product for public release. Apple is expected to formally introduce the next iPhone at its WWDC event in June.
