I downloaded pwnage tool 4.0 and followed the instructions
i downloaded iOS 4 a few days ago,
have itunes 9.2
and when i try to restore it with my custom restore (opt+restore on itunes) it prepares it to restore for a while, then brings up the unknown error 1604
I ahve never jailbroke or anything before, is there something i have to do before using pwnage tool 4.0 that i'm missing?
