I know this is a commonly posted thing, with lots of solutions scattered across the internet but non of them work . I was updating my mac and stupidly whilst clicking everywhere hit update in itunes for my iPhone 3gs (jailbroken) and now i get the USB to itunes screen on every load up. I've tried: iRecovery Pwnage tool Tiny umbrella to restore it to some form of working firmware but either i am being a newb (highly likely) or nothing works!! I can't put it into DFU mode (trust me i've tried). It was on 4.2.1 I think. Anyone got any answers ??
