My iPhone 5 suddenly quit allowing me to log in.
My iPhone 5 suddenly quit allowing me to log in. It'll bring up the entry screen as normal but as soon as I touch the first button for log in the screen goes dark with a little circle in the middle going around. I tried a shut down with the same result. I called phone from another number and it rings but won't allow me to answer the call. Any ideas out there?
