This is an example of how to get unlock your Iphone 4 32 GB from At&t. I got my unlock code from cellunlocker.net To input the unlock code you: 1. Input a non accepted simcard into the phone. 2. The phone will ask you to enter the unlock code. 3. Enter the unlock code. Your phone is now unlocked. Thats it! Thanks Cellunlocker.net!
