Canadian carrier TELUS has confirmed that the HTC One will be receiving the Androd 4.3 Jelly Bean update before everyone else (except the Nexus devices) as early as next week. Residents of Canada and the US should be receiving the update in the next few days itself.
HTC has outdone themselves this time by delivering on software updates, a department that the Taiwanese company has been traditionally lacking for some reason (Sense UI is pretty heavy, and difficult to port to new Android iterations quickly). Mind you, the Android 4.3 udpate for the West will come with the same Sense 5.0 overlay, while the international HTC One Android 4.3 update (which is scheduled for sometime next month) will bring the updated Sense 5.5 UI.
Certainly an exciting time to be a HTC One owner.
