I recently upgraded from an iPhone 3G to an iPhone 4S.
I always had perfect network coverage with AT&T at my apartment with my old iPhone 3G.
But with the new iPhone 4S I can't receive or make calls in my apartment. At home, the iPhone shows 5 bars reception which occassionaly switches to 'No Service'.
The weird thing is that when I'm on the phone as I walk into my apartment from outside, the call doesn't drop. But as soon as I hang up and want to make/receive another call, I get the 'Call Failed'. My girlfriend who lives with me has the same issue with her iPhone 4S.
Any ideas what's going on?
