He first erased all content and settings, then tried doing a restore thru iTunes and gets error 1403 and the iPhone gets stuck. I think he is on iTunes 10.1 so it's not the latest, and I assume this is the issue. It's probably trying to ask for 4.3 and can't accept it?? Anyway I want to know if it's still safe for me to buy it and attempt to restore myself.
