iPhone 4S is frozen on "Not Enough Storage" message...
My iPhone 4S is stuck on the "Not Enough Storage" message. It won't let me do anything, and I can't power down becuase my sleep/lock button is stuck. I do have assistive touch, and when I go to Device, and hold down the "lock screen" key, the power down screen comes up, but becuase of the "Not Enough storage" message frozen on my screen, I can't slide to power off. What can I do?
iPhone 4S, iOS 6.1.2
