My 'Pad went back to 3G. :D Not sure why, I did let it run all the way down to auto shut off then recharged back to full. Turned it on and I have full 3G connection and speeds. I wonder if Awful Telephone and Telegraph "fixed" something.....
I got my iPad replaced. The replacement came with 3.2. Haven't had one disconnect yet.
Try this... If you're jailbroken and using SBS Settings, swipe finger from left to right across where signal bars and ATT carrier logo are. A screen will pop-up for the SBS options like re-spring. There's also a 3G icon... Make sure yours isn't disabled (red) like mine was. Tapping to make it green worked like a charm. 3Gcame back to life in an instant. Hope that helps :)
I've driven cross-county with iPad 1 and 2. When they switched to Edge, they automatically kicked back to 3G when I got closer to a tower. That was true the whole way across the county. I never had to do anything to kick them back to 3G. Both of mine are AT&T.
My iPad suddenly stopped recognizing my sim card...pls I need help!
