I have been having data issues since Friday. I got it back yesterday by hard resetting the phone but when I called to enable visual voicemail, my data connection dropped completely and my phone was just showing bars but with no 3G, 4G or E data connection indicator. I have talked to a couple of AT&T reps and they were unable to help me. The store rep I talked to said I can come in tomorrow to replace the phone and he mentioned that he had two other customers with similar issues. I finally tried monkeying around with APN settings tonight and got my data connection to work finally. I don't know how long this will last though but if you have data connection issues like me, here is what I did
1) Go to Settings-Cellular and and click Add APN
2) Use the following APN settings (enter it exactly like this)
APN -> phone
Username -> leave blank
Password -> leave blank
Proxy server/URL -> proxy.mobile.att.net
Proxy Port -> 80
3) Click the check button to accept the the settings.
4) Turn off wifi so you can verify later if the data connection is now working
5) Turn off your phone and turn it back on
6) Wait a few minutes and check your data connection. I think mine suddenly work after about 10 minutes or so
Its weird. Give this a try and see if this works for you too.
