Hi All, I have an ip4 and I can't get cellular data. voice, txt msg and even location services works fine. But I can't seem to get data. It gives the popup that it can't connect to cellular data mesg. I have tried all resets, settings and networks, restarting and the home and power button restart. Anyone else having this issue? Att and apple were not able to help over the phone. ip4 is not jailbroken Thanks!
