Just caught wind of this over @ T-MO NEWS:
Software update: HTC One (LTE) | T-Mobile Support
HTC One software update released, LTE data and reception fix included | TmoNewsTmoNews
Again,this is not the 4.2.2 UPDATE,just a maintenance update.
Looked for it on HTC's website,as directed by T-MOBILE,if you don't want to wait for the OTA.No sight of it so far...............
Got the update OTA,installing now.....
As the notes state,not expecting anything earth-shattering,epecially since LTE isn't deployed in my area ATM.
