I accidentally left my iPod touch 4g on all night on an alarm clock app. When I woke up it was stuck on a loop where it goes to the lock screen for 2 seconds and then back to a black screen with an apple on it for 6 seconds. I can not get it out of this loop this sequence flashes back and forth continually until the ipod runs out of battery. I can still sync the iPod and it is still recognized by the computer. I have tried restarting it and turning it off doesn't work. I have even restored the iPod's software and it still doesn't get out of this loop. Please help me!!
