I'm looking for some advice. I'm new to the iPhone but got the 3GS when it came out. I've looked after it (case and screen protector) since i got it but this morning when I got up it seems to have switched itself off and won't turn back on. I've tried plugging it in with the AC adapter and also to my laptop to see if it would sync but neitehr has worked. Doeds anyone have any ideas other than take it and aplle store and get a genius appointment?
