HTC ONE X plus Android 4.2 Sense 5 Update Rolling

Out In ASIA

According to reports from XDA and VR-Zone it's only unlocked devices in Asia that are receiving the update at present, but Europe and (eventually) the U.S. should follow before too long. (And we're sure you'll be able to find a custom ROM or two out there if you can't wait.)

The hefty 484MB over-the-air package now going out will update Asian HTC One X+ devices to software version 2.17.709.12.
