Here I describe the method that I performed when I tried to officially unlock my device via iTunes after using SAM. In my previous post I showed you the best way to unlock iPhone using SAM on iOS 6. After this article many iPhone users factory unlocked their devices. But there was one problem after restore with iPhone activation after factory unlock. iTunes didn't detect iPhone. The problem is in SAM unlocking tool and IMEI / IMSI number. When you hack your iPhone 4, 4S, 3GS and 3G using SAM you change your IMSI number and that cheat Apple and you can use other carrier/SIM card on your device. After Apple closed this exploits it was not possible use it except you have activation tickets.
