Silently HTC has managed to push update for its powerful smartphone, the One X, making the device running on Android 4.0.4 with Sense UI 4.1.
It is OTA update and the total file is 148MB. You should connect to WiFi network before downloading it. With the update, homescreen, web browser and image quality of camera and notification bar were improved.
If the update is not available in your country yet, you better wait a little longer more since now it is only available in Germany.
