I've had my Iphone 3GS since a week after it came out. I turn my phone off every other night to let it rest, and such. The past few weeks, I've had trouble turning my phone back on. It will get stuck on the Apple Screen and turn off, I try to reset it by holding the Wake/Sleep button or reboot by holding the wake/sleep and home button. Nothing works sometimes. So then I have to Reset the whole phone from Itunes. Has anyone else had this problem?
