The HTC One X Android 4.1 Jelly Bean update, which HTC promised would be rolling out this month, has apparently started rolling out as promised though it appears that the roll out for the moment is only limited to Taiwan, HTC’s home.

According to a post on XDA-Developers forum, the update is apparently rolling out in Taiwan and the version is reported to be version 3.14.709.16 with a size of 352.87MB. That’s a sizable update and means that those who are lucky enough to receive the update today will want to take some time to download and install it.

Once up and running the version of Android is said to be Android 4.1.2, the latest version of Jelly Bean.

As for the HTC One S, which HTC said would start to see Android 4.1 Jelly Bean this month as well, nothing was announced and its release date remains unclear at this point though we’d be surprised if HTC missed the October cutoff.

We advise those who have yet to receive the update today to remain patient. This is clearly an initial roll out and it will take some time before the update moves to different regions in the world. It’s no surprise that the company started with Taiwan as that is where HTC is based.

As for the update itself, it apparently brings not only Android 4.1 Jelly Bean, but HTC Sense 4+ as well which is the company’s user interface that comes over the top of Android. In addition to the new UI, the update will bring all that is Android 4.1 Jelly Bean.

Starting with its smooth and faster user interface, Android 4.1 Jelly Bean is a huge upgrade over Android 4.0 Ice Cream Sandwich, the software that the HTC One X launched with.

It also comes with improved Notifications, Google Now, improved Calendar and Browser, more camera functionality, new Face Unlock features and more.

Still no word about updates for the AT&T HTC One X or HTC One S Jelly Bean updates but now that this is out, it’s a sign that we could see some progress soon.
