My wife's iPhone 4 started acting messed up out of the blue. You can't swipe pages or slide to scroll, everything you touch it speaks to you and tells you what it is, even when you click on the signal strength it says what it is, to open or activate any apps on first page (can't swipe to second page) you have to double click on it, and when "she" talks to you, she tells you to double click. The Internet is the same way when pulled up, can't scroll and whatever you touch it speaks to you and explains what it is. Any ideas????
