Agree I still don't get why this was last compared to other career version. I mean first you develop the update for your base firmware which means it should be ready for the unlocked non carrier version, then you apply that or modify to the million different customized crappy carrier firmwares.
I'm not sure why we won't get way before the carrier ones but hey atleast it's an improvement this year that we are getting updates close to carrier models unlike previous years where unlocked US model updates were non existent.
