Since the iPhone 3G already has an ARM processor, that has led to speculation that Apple are currently making an entirely new chip custom designed for the handset’s specific needs.  That would certainly fit in with Jobs’ assertion that having an in-house CPU facility would allow for specially tailored silicon.

Such a chip could integrate not only the basic core but also multitouch touchscreen support, graphics acceleration and other device-specific features, which would make the CPU more efficient and reduce the number of other chips required in future iPhones and iPods.  Apple declined to comment on the rumors.
