My brand new 2 week old itouch crashes about 2 or 3 times a day, it complietely shuts down, restarts, frezes on the apple logo starts glitching very badly, and it won't go back to normal untill I put it to charge. it used to only do this while I was using safari but now it does it radomly. it started to do this about 2 days after I installed the newest avalable software, I don't know how this started happenning I haven't dropped it and I have been as careful as I could with it. please tell me whats wrong!
