I am still confused. I have an icon saying I can do an update from verizon. Its roughly 90 mb and I am guessing its a 2.2 update. My phone has been acting up a lot and I think I will need to do a warranty claim soon. I am rooted, but no custom roms or anything. I just did it for wireless tether mainly. If I install this update, will my phone be unrooted/able to be brought back to verizon without anything else?
