Hi, I'm new to the forums, I'm hoping you guys can help me solve a problem. Last night I full charge my phone, unplugged it and went to bed and everything was fine. This morning I wake up and press the home button to get to the lock screen and just when I was putting the last digit, the itouch shut off and now it's displaying the apple logo then the battery logo back and forth (It's jailbroken but I jailbroke it a while ago, I'd say since around when 4.2.1 came out). Edit: Just an added detail, the computer can't detect the itouch now. I've also tried to press the sleep and home button at the same time, but it still won't work. Thank you!
