my phone needs an upgrade. i haven't modified it since back in september of 2010 when the froyo leak came out, and i'd like to get up to speed with the best of you. currently, i'm running a rooted 2.2 DX on the 2.3.9 system version, and i'd like to be updated, yet still able to receive OTAs. outside of unrooting, what else do i have to do to get to the latest level? thanks in advance.
