Anyone else getting this error? I called AT&T twice and they verified everything on my account. They said there is nothing else they can do. It's been 6 hours since I got my phone and am not sure if I should keep trying to activate it or wait and see if it works. My previous phone was the 1st generation iPhone and now it no longer works since I tried activating the new iPhone 4S...Hence at the moment I am without a phone and very unhappy. Any suggestions/tips?
