Help!!!!! I've been using 1.0.2 FW iPhone for two months now. I jailbreaked my iphone (I didn't unlock) and am using AT&T. For whatever reason, I update my firmware to 1.1.1 and it said "SIM Locked" and asked me to connect to iTune. I did just that and iTune asked me to insert a valid SIM I didn't restore my 1.0.2 to factory setting prior to updating. Now I can't do anything with my iPhone. I put my iPhone SIM on my old GSM phone and it worked. Any idea on how I can get my phone to work? I can't even get pass the Activation screen. Gah!!!!!!!!!! what was I thinking
