Iphone 4s will not restore
Please help. Last night my brand new iphone 4s froze. I tried to turn it off by holding down the home and wake button. I've plugged it into itunes and tried to restore it, but when it is preparing to restore it the phone turns off. When I try to turn it on the apple logo appears and then goes straight to the connect to itunes page. After 30-45 seconds the iphone turns off again. It will not come on, what can I do to get it to work?
iPhone 4S, Windows 7
