HTC delivered some bad news for HTC One S owners today by confirming that the device would not be upgraded to Android 4.2.2 with Sense 5. Despite being just over a year old, the device will now have stick with the software it already has.

The much-anticipated Android 4.2.2 Jelly Bean upgrade for the flagship HTC One has begun its rollout in Taiwan, just days after making its debut in China. The over-the-air release weighs in at 465MB and introduces a number of key new features.

Verizon customers have been patiently awaiting the release of the HTC One since it was confirmed in early June, and although the carrier promised it would be here “this summer,” we’re still yet to see a more specific release date. The device has now appeared in a leaked press image, which suggests it may not be available until September.

An Android 4.3 Jelly Bean ROM was leaked earlier this week and much to our surprise it wasn’t for a Nexus device. The leaked ROM was for the Samsung Galaxy S4 Google Edition, and was subsequently ported over to the standard GT-I9505 Galaxy S4.

There are very little user-facing changes in this build, however, since we don’t know how long it will be until the final build is released, we could very well see some more changes in the official Android 4.3 build when it comes out. Here’s what’s changed so far.

The long-awaited Android 4.2.2 update for the HTC One has started its rollout on the Chinese dual-SIM version (M7C-DUC). It is rumored that the international versions — including those in the U.S. — could also receive this update sometime later on today day.
