Android update weighs in at 364.54 MB.
HTC had previously promised that its One X smartphone would receive the Android 4.1 Jelly Bean update. Singapore and Taiwan users were the first to be offered the updated version of the mobile operating system, and now it's rolling out globally.
HTC One X owners situated in the United Kingdom, Russia, India, Argentina, Brazil, Peru and other regions are now able to download the update over-the-air. Other countries should receive 4.1 Jelly Bean imminently, a HTC source said.
Those who have yet to see an alert pertaining to the update can navigate towards Settings > Software Updates > Check Now. An initial 1.6MB file will be delivered, followed by a 364.54MB Android update.
The update itself sees the user interface becoming faster, which particularly applies to the switches of orientation from portrait to landscape. In addition to Face Unlock being more accurate than previous versions, users can also switch between apps faster.
Android 4.1 Jelly Bean also delivers Google's improved voice search, as well as Google Now, a service that provides information based on your location, appointments and schedules.
The aforementioned version of the operating system isn't, unfortunately for HTC users, the latest iteration of Android. 4.2 Jelly Bean is now available on the Nexus 4 and Nexus 10.
During the last two weeks of October, Android 4.1 accounted for a 2.7 percent of the market share.

Google makes an OS, and then says "software and hardware isn't our problem"
HTC et al makes some hardware, then says "the OS and software isn't our problem"
Millions of random hacks make some software, than say "the OS and hardware isn't our problem"
And then, like in many committees, it takes a lot of time to get nothing done. The software is fragmented and poorly optimized (if it works at all), the hardware is underutilized and far too expensive for the given experience, and the OS moves too fast to give programmers time to make anything worthwhile.
The only place such type of technology works is at the very bottom of the price spectrum, and for script kiddies to experiment. For people that want things to work reliably, with little input from them (which is the vast majority), a more thorough approach is needed.
Who cares that the Android OS is one digit higher now? What does that mean for the user?
I do agree with you on the last point, who cares if your OS is one digit higher now. Because from what I can tell, mobile OS has hit a wall, there are no more killer features, this include Android and iOS. My iOS friends totally wish they haven't downgrade from iOS 5 to iOS 6, they were "perfectly" happy with iOS 5. I recently upgraded my Nexus 7 to Android 4.2, was excited for 10 minutes, my Galaxy S3 was upgraded from 4.0.4 to 4.1.1, I was excited for 15 minutes.
As far as OS moving too fast? lol
Tell that to my brother and my gf, their words, "iPhone is boring~". They'll be switching over to Galaxy S4 or Note 3. I said the same thing about 2 generations ago, dropped the iPhone for a Galaxy phone, never looked back.
When I owned a Motorola Droid, I felt abandoned. I guess that's why iOS users stay with iOS. For me it was a no brainer to go with Android because customization and side loading apps are 2 of the most important features I wanted. I don't want a phone like everyone else. I want a phone that only I know how to use. It gives me a sense of power to have control of my property.
The reason why I switched to a Nexus was because of updates and I was able to chose the GSM carrier I wanted without a contract. Updates makes me feel as though Google still cared for me. Phones get outdated quick today so I'm really hoping my GNex will good for another year or more because it is still a very capable device.
I think the general population will have to demand more before Apple does more. As long as iPhone sales continue to be off-the-charts, though, Apple has little motivation to bring a more contemporary UI to iOS. I'd like to see not only this but them also correct the build quality issue they're currently experiencing with the iPhone 5. ...then I might be interested again. Until then, Android is my friend, for I am loyal to no technology.
