Hmmmm... interesting thing happened. I decided to give in to the OTA and follow the re-root steps. The phone indicated the update would be starting. But then it went to the home screen and everything is as it was. I'm still at 2.2. Apparently the update didn't happen. I looked at the "system updates" screen and it says "Your system is currently up to date", where before it indicated I had the update waiting for installation.
So do I leave as is... "well enough alone"... hoping to not get bugged about OTAs again? Or should I look for the stock Gingerbread ROM for installation?
