My friend has a 2G iphone. updated to 2.0.1(I believe) a while ago in itunes with no sim card in the iphone.
The phone then asks for a sim card that does not have a pin lock on. It says emergency calls only.
So to fix it, can he put the phone in DFU mode if he can only make emergency calls?
Then restore to 2.1 or 2.2 and then use quickpwn?
