PLEASE HELP! I have jailbroken my iPhone 4 (tethered ios5.1), and when it turned off, I can't even boot it tethered with redsn0w (I am not able to turn off the phone) because when i plug it into PC (phone ran out of battery), phone starts up, and then everytime like 3 seconds after appearing lockscreen, it starts loading. I can't do anything about it, cuz the loading cancels my every action. Thanks for help..
