Apple A4 processor found in next-gen iPhoneThis article contains unofficial information.
Thanks to today's appearance of the next-gen iPhone in Vietnam, we now know what processor is hiding inside the hot smartphone. Engadget reports that the label "APL0398" found on the chip is also found on the Apple A4 processor of the iPad, so we now have a pretty solid reason to believe that the fourth iPhone will be powered by a 1GHz microprocessor, as it was once speculated. Now that's what we call good news!
Additionally, Pocketnow suggests that the screen of the phone, showed in the hands-on video, uses a new technology, probably AMOLED, due to its seemingly great viewing angles. However, we would rather place our money on Apple having used an LCD IPS screen, as in the iPad, since it also provides a very good viewing angle. Fortunately, there isn't much left until we know for sure...
