HTC Sensation XL Android Ice Cream Sandwich 4.0.3 Update is currently Rolling-out to all unlocked Sensation XL devices.
As you can notice from the screenshots above, the smartphone gets updated to ICS version 4.0.3 along with HTC Sense 3.6. That's pretty nice treatment for a device, whose hardware is a bit far from being cutting edge even by last year's standards.
To Update, Connect you XL device to Wifi and you will get a System Update Notification, Click Update and ENJOY!
