I got an ipod touch yesterday and this morning i went to turn it on and it wont turn on. I plugged it into the computer to see if anything would happen and all i got was the sound when it connects to itunes. I was wondering if i had locked the screen somehow. Is there any button that slides to lock or something like that. Obviously as it wont turn on it could possibly be faulty. Please can somebody help me. Any replies will be highly appreciated!
