I know this has been asked, but I confused. After I install SPrecovery I made a back up this would be in the unrooted mode. If I want to go to the OTA 2.2 update can I use SPrecovery to go back to that time frame and wait for the Over the air update to show up on my phone? Or do I have to also get sprecovery off as well. I would like to keep it on as it is a great back up.
