What must I do yo unlock my iPhone4? I say locked, because, all of sudden AI can't open any app, including settings, or school screen. Also, a voice repeats name of any app I touch, with a black rectangle box around app. It says double tap to open, but it doesn't open? Help!
iPhone 4, iOS 6.1.4, Not sure if IOS 6.1.4 correct?or .6
