iPhone 'phone app' issues
Help! My phone seems to be working fine - with one critical exception. The phone 'app' is unresponsive. It seems to open ok, but nothing responds to the touch screen so i can only make outgoing calls by searching for a contact in the home screen search and calling from there. I can't type a number into the phone. Its been like this for the last 24 hours. I've rebooted a few times, but the problem seems limited to that application. Any ideas?
thanks
