Same here, did the manual update a couple days ago, had Sprint notification today that there was an update but it went away shortly, I checked System Updates/Update Android to make sure and of course it said my system was up to date.
Rooted my phone today, except for a small glitch where the SD card wasn't detected (had this before when rooted and running ACE Rom) that was fixed on reboot, things have been running smoothly, definitely quicker with better battery life.
Looking forward to some new GB Roms. Was on the verge of selling my Epic and getting an Evo 3D, but think I'll hang onto it for awhile (not eligible for a new phone 'til next May), as the long-awaited Gingerbread has been a pleasant surprise.
