I am trying to use redsn0w 0.9.9b6 with iOS 5 and a Verizon iPhone 4 of course. The baseband is 3.0.03 and whenever i try to jailbreak it on my macbook, it ALWAYS freezes on the "waiting for reboot" stage. I try to put it in DFU mode and the screen just goes to a backlit black... i have the latest version of iTunes and everything... what am I doing wrong??????
