The Android 4.4.2 KitKat update for T-Mobile's version of the Samsung Galaxy Note 3 has starting rolling out OTA now. Don't forget that these rollouts go out in batches, so you may not see it on your device for a few days. If you want to try and grab it manually, you can tap Settings > General > About device > Software update (of course that doesn't always work either).
Regardless, when you do eventually get the update you will be on software version N900TUVUCNB4. There's nothing really unusual in this update beyond what you get in 4.4.2 KitKat. Sound off if you are one of the lucky folks who have received this update.
