Hey guys and gals. Hope all is all well. I was wondering if you could help me out with my iphone please. I have an iphone model #a1203, I do not have service on it. I was on itunes and saw an upgrade was available, so i upgraded and now it is asking for the sim to activate. The phone was never a jailbroken, or modded. Would i have to get a att sim to reactivate? I tried doing the restore with a previous fw but it shows an error. any help would be much appreciated.
I am running XP, and the newest version of itunes.
Thanks again.
ps what is the diffrence between 2g and 3g?
