So, I sold a JB & UL 3G on 4.1 with the iPad baseband yesterday and it worked great when they left. They called me today saying that it won't get service now, so here I am trying to figure out WTF the problem is. What I know: - Its not the sim card. - Its on 4.1 - That's about it What I've done: - Tried a restore with custom 4.1 FW using redsn0w. Cydia was still installed after the restore. Is that normal? I'm having really bad luck these days. If I can't fix it I'll have to buy back the phone. Not a huge problem since I have the cash, but still. Thanks in advance for the help.
