My older Iphone 4 was plugged in all night and was fully charged. Went to use it as I tried to send a text. Error came up stating that I had to restore it via Itunes. In all my wisdom; I decided to reboot it to see if that would fix the problem. Not! It is now stuck with a black screen and showing the Apple logo. I hooked it up to Itunes. Itunes asked me if I trusted this computer to access the information on my Iphone. I said okay. It than asked me to confirm this on my Iphone. Can't do that; the phone is stuck on the black screen. Any solution to this?
