Been using NCSettings on my 4S (6.1, AT&T) for a week without issue. Today it showed an update to 1.7.1, which I installed. Now I have no cellular data connection even though it shows full bars and 4G. I know there were issues with the new 3G toggle but my question is how I undo the damage. I have reset network settings, done a hard reset, uninstalled NCSettings, etc. Nothing has helped. I did I search but didn't see any answers. Would anyone know how, short of a full restore (which I would love to avoid because I have had good luck with 6.1), to get things back in order?
