Will Apple's A4 iPad 1GHz chip be used for the iPhone?
Since the Apple A4 was designed for mobile devices, and with the similarities between the iPad and the iPhone, it wouldn't be a stretch to imagine the 1GHz chip powering a faster generation of Apple's touchscreen phone. Nathan Brookwood, an analyst at Insight 64 says, "There's really no reason why a chip with this kind of characteristic wouldn't make it in the iPhone." Apple could even underclock the A4 in a new generation of iPhone which would allow for greater battery life. Currently, the iPhone 3GS uses an Arm based system on a chip produced by Samsung clocked at 600MHz.
