"Then I noticed that the bars would drop to zero and come back with the E (edge) symbol. Then it would go to NO SERVICE. And then a minute later back to 3G but still no ability to use the phone. Nothing including turning off the phone would help.
On Tuesday I was at the town center and again having issues so I went to the Apple Store to test one of their phones in the store. Before I could even get to a phone, the Apple Store Greeter guy asked if I needed any help. I explained the issue and he immediately said they were aware of the issue with AT&T. No one in the Apple Store could use the network or was able to make calls at that location! Wow. Bad."
