Why does my Data not work for my iPhone 4S?
My iPhone 4S has over the past month not been able to use data for any of the applications I have including iMessages, maps, email, and the web. I use AT&T as my carrier, but I know that other people have had the same problem on other carriers. I am not sure how to resolve this problem and it is really frustrating when I am paying for a data plan, but can not use it!
iPhone 4S, iOS 5.1.1
