Hey, After buying an off-contract iPhone 4S, my wife decided she would rather stick to her original iPhone because she prefers the design of this Anyways, got a brand new Sim from an AT&T store, came home, popped in the original iPhone, activated it (selected the unlimited data as we had before), once it was done all I saw was a blank screen. The phone shows the connect to iTunes icon and the slider says : slide for emergency. And that's it. I can call and text that number, but if I slide the slider, all I can do is make an emergency call. Help please? ps: yes, I have already tried to restore the phone twice, that doesn't help. What can be wrong here?
