The iPhone has the usual GSM and Wi-Fi antennas, battery, tape and camera. As well, it uses 2 PCB cards – each tightly packed with chips. It also equipped with the Samsung MLC NAND and an ARM processor. However, the ARM processor bears the Apple logo not the Samsung logo, who manufactured it.
The touch-screen consists of multiple layers, with the layer closest to the motherboard having faint dots in a grid like pattern.
However, Anand Lal Shimpi was not able to put the iPhone to function. He also warned not to do this as it may void your warranty. (Maybe get two iPhones if you plan to do this…)
