I unplugged my IPhone from the car charger and it was fully charged. It kin of hung up on something and I couldn't get it back to the home page so I thought if I rebooted it, it would help. Wrong! Now it won't tune on. I have held the on button for a length of time and I have just hit it for a second or two, and still nothing. Any body out there have any suggestions or has experienced this problem? Any advice will be greatly appreciated.
