My iphone 4S got stuck. The screen shows a sign that I must connect it to the iTunes.
I tried to update my iPhone 4S but I couldn't... the iTunes screen shows a message of error. Now, my iPhone got stuck on a screen that shows I must connect to the iTunes. I tried all kind of tricks to put my iPhone back to work, including physically disconnecting the battery. None of the actions solved the problem. Do you know what can I do to solve this problem? Tks.
