Q: Has anyone else lost 3G connectivity after upgrading to iOS6? My O2 account is active for 24 more days but iPad is showing "no service".

I have managed to fix this myself by doing a powerdown and reboot of my iPad. As soon as it booted up the cellular service returned. Saved me a trip to an Apple store and some poor technician getting an ear-bashing. It makes me wonder if Apple actually test their upgrades.
