Recently, yet another iPhone 4G leaked over Veitnamese forum. Guys over Taoviet dismantled it completely, which revealed some concrete information confirming the veracity of the device.
If you closely see the marking on the chip with the Apple logo, you will notice “339S0084″. According to Chipworks, this is the Apple A4 microprocessor fabricated by Samsung and the presumed work of Apple’s acquired PA Semi and Intrinsity engineers. The “APL0398″ text is also the same available on the iPad’s A4 system-on-chip.
