I am a regular customer of AT&T and just didn't want to pay the extra monthly....SO I unlocked mine. Well today I noticed "no service" on my iphone. I then Ibrick and unlocked my iphone like I did before. Nothing! tried it again...Nothing! I then learned when I went on my AT&T account...THEY know that I have an iphone. WTF? now what? They are giving me a unlock code but I don't even know how to put that in. 8 digits. I tried to enter it like a phone # and even went to the settings...NOthing! HELP!
