So I recently transferred my JB iPad 1 data to my new iPad 2, and upon using the 3G, I can only get edge, no 3G. I have 5 bars, but no 3G. The only thing I can think of that could be the problem is my JB iPad 1 had SBSettings installed, and both 3G and Data (the E icon) were switched to off when I made the backup for my iPad 2. I tried only turning on the E icon in SBSettings, but for some reason it keeps saying No Service... I guess I've got to switch them on again and make another backup? Unless there's a way to access the 3G switch on official firmware.
