HTC stated in a press release on October 2 that both One X and One S users would receive an update during that month to Android 4.1. Although One S users weren't so lucky, select One X users did see the upgrade, with consumers in both Singapore and Taiwan successfully upgrading. Now other One X users can rejoice, because it appears the update is being rolled out globally.
Now, according to tweets appearing across the Twittersphere, users all over the world are successfully updating their HTC One X handset to Android Jelly Bean. According to HTC Source, the update is reaching both CID_038 and CID_044 handsets for users in Russia, the UK, India, Argentina, Brazil, Peru, and more. The update will likely hit other areas soon.
The update is OTA, but you can try to nab it manually by going to "Software Updates" -> "Check Now" under Settings. The update originates with a 1.6MB file, followed by a larger 364.54MB Android update, which is a bit smaller than the first round of updates that appeared. Once updated, One X users will have access to a variety of new features.
The Jelly Bean update brings with it a faster user interface that boasts snappier orientation changes and more responsiveness when toggling betwixt apps. Rendering is more consistent, and there's reactive touch for improved battery life. Face Unlock is more accurate than in previous iterations, certain SSIDs can be designated as mobile hotspots, and users can swipe from the camera viewfinder to easily review photos.
