We were so busy today that we just missed out on one of the goodies for today that all HTC One users are up for in the next week. HTC One users on T-Mobile will be able to experience and use Android 4.3 Jelly Bean on their device as an update for the same is scheduled sometime next week as per Jason Mackenzie ( President of HTC America ).
Just a heads up that we are still on track (barring some last second issue) to update your T-Mobile One with 4.3 by mid next week.
