I have upgraded to 2.2.1 through iTunes and also used QuickPwn to Jailbreak and Unlock the iPhone. The problem is that it isn't unlocking the phone so I went through Cydia and downloaded Bootneuter 2.1 and when I go to it, the screen freezes and i can't change any settings (not that I want to) or even click the flash button. This has happened about 10 times and not even holding the power button will escape the program. Can someone with solutions for this problem please help?
