The Android 4.4.2 update for the HTC One on T-Mobile and AT&T is nearly ready. HTC’s Jason Mackenzie answered a few tweets early this afternoon, indicating that the T-Mobile HTC One Android 4.4.2 update will be available later this week, but AT&T is taking its time to thoroughly test the update and will most likely push it out to its HTC One customers during the last week of February. HTC originally planned to release the update for all US variants of the HTC One before the end of January, but carrier testing has taken more time than HTC had anticipated.
