Ok here is what happened. I bought a first generation Iphone on ebay. It was jailbroken 1.1.4 and I had planned to jailbreak to 2.0. It didn't have a simcard. I bought a new AT&T simcard on ebay as well and purchased prepaid service for it. The iphone was working, still on 1.1.4. I was looking into how to jailbreak it to 2.0 - wanted installer and the app store - when without my knowledge my brother tried to jailbreak it for me. I don't know what exactly happened but now when I plug my iphone into my computer and itunes, it wants me to activate it with AT&T. It won't recognize my prepaid service. Now all I get is the plug into itunes symbol and nothing else with the iphone. I don't think my brother backed up my iphone, and I have beaten him several times and I will never let him touch anything electronic of mine again. What can be done? I don't care what firmware I get as long as I can get the iphone to work. I'm at my wits end. Please any help appreciated!
