The new iPad constantly losing cellular data connnection
My new iPad (3rd gen), 4G (AT&T) cannot seem to maintain a cellular data connection. The AT&T signal meter is still there (and shows 3 bars), but the "4G" disappears, and I get a "could not activate the cellular data network" error. I know it's not my location because it happens both at work and at home, and because my iPhone 4S and 1st gen iPad don't have the problem. I have already toggled cellular data on and off, restarted the iPad, reset network settings, and restarted again. No luck. Each time I restart, the connection works for about 30 seconds, and I can check my email, but then it immediately goes out again. Has anyone else had this problem?
iPad, iOS 5.1
