HTC recently released the Android 4.0.4 Ice Cream Sandwich (ICS) Over-The-Air (OTA) update for the international version of One X which was announced at this year's Mobile World Congress. An interesting feature the update brings is the Sense v4.1.

The OTA update is yet to make its way through all other regions. Developers have come up with a new ROM to update the device to Android 4.0.4. Mike1986, a well known developer from XDA, has released a ROM-Android Revolution HD 9.1.0-which is based on Android 4.0.4 (official firmware version 2.17.401.2) for One X. The ROM is said to be delivering faster performance and brings HTC Sense 4.1 as well.

The One X can be now updated to Android 4.0.4 (Ice Cream Sandwich).

"Feels a lot smoother in use-scrolling, swiping between sense screens. Much nicer feel. This is a real good one, Mike. Many thanks," a member from XDA Developers by name dsm52 has been quoted as saying.

Some of the features the ROM brings along with the new update include removal of software (CPU) rendering, optimised RAM, enhanced camera as well as virtual memory management, GPU user interface (UI) rendering, improved CPU performance and battery life and Adobe Flash Player support for ICS.
