I tried jailbreaking my iPod with snowbreeze 2.1 I made the recovery file,but I must have made a mistake while putting my iPod into DFU mode.My screen turned white and now I restored it to factory settings.Will I have to make a new ISPW file and redo the DFU process or can I use my ISPW file now to jailbreak it by just holding shift and pressing restore and using the ISPW snowbreeze file?
