My iPhone 4 suddenly stopped being recognized. It will not connect to my usb in my car, my wall charger or my computer. I've tried different usb cables, and the problem still exists. I have not recently backed up either. Will I lose everything? I have tried turning it on and off. I do have an appointment at the genius bar, but I still wanted to see if anyone had any other suggestions. I am afraid I am going to lose all of my photos. Will I be charged for another phone if it is broken and cannot be fixed and my warranty is up?
