I just got an iPhone from a guy and wanted some help unlocking it or to be pointed in the right direction. I have done some searching and reading but none that has worked in success. I have firmware 1.1.2 and the guy has had the phone for 4 months before me so I assume thats not the origonal that came on the phone. Can some of you guys help me, I want to be able to change my main screen buttons with new Apps, and change the background from black to a photo. Please help, thanks!!!
