Here's the deal.. I was driving today and all of a sudden my phone just stopped working.. I saw a notification saying I should restore my phone or contact apple.. My phone still powers on, I still have my custom lock screen and all but I can only make emergency calls and access SBSettings which doesn't actually work anymore. So I tried to restore the the custom firmware and itunes keeps giving me the 1600 error .. I have heard iReb can fix this but I dont even know if its compatible with the 3GS for this issue.. I have tried but its kinda confusing and hasnt exactly worked.. anyone know anything I can do?
