HTC One
Android 4.2.2 is apparently rolling out to the single SIM version of the HTC One in HTCs home country of Taiwan as an Over The Air updated, after reports of the 4.2.2 update began circulating that the Dual-SIM HTC One was receiving the update a couple of days ago.

The 465MB update is hitting the international version of the HTC One and according to the people who’ve received the update it brings about a slew of new updates. The image below from Android Central shows the list of updates included, which address things such as the menu bar as well as adding battery perentage in the status bar, Quick Settings, a new Lock Screen style widget and more :

In terms of the updates availability to HTC One owners who purchased their device through a carrier, the update is apparently already in testing with Vodafone, while Telstra are apparently still ‘Waiting for initial vendor submission’ and Optus has not updated their updates page nor their forum with any information with regards to the HTC One.

We’ll update as soon as we see any updates from the carriers, but those of you who purchased an International unlocked version of the HTC One, your update should be here fairly soon.
