I've been using redsn0w for my recent jailbreakings of A4 processors. When I was trying to jailbreak a friends phone it got to the part after DFU mode where its waiting for the phone to boot up. Once it gets here the phone actually boots up! Redsn0w then decides to freeze up. Would any of you be able to tell me why it worked for my phone, ipod, and gf ipod, but not this phone?
