Owners of the HTC One X (XL) on AT&T have just noticed a sizable updated headed their way, coming across prompts from their phones that a 270MB update is now available. While there’s no official changelog available, users have noticed a number of improvements in this Android 4.0.4 update, though it’s not entirely good news.

Besides bringing the phone up to Android 4.0.4, system software 2.20 make some changes to the depiction of the phone’s menu bar in certain apps, where it would appear as an ugly back space. This release cleans that up, as well as provides new contextual behavior options for the phone’s recent apps button. Users are reporting an improved multitasking experience, and the impression of brisker operation with reduced lag.

So what’s the problem? The update appears to close the holes currently used by developers to root the handset. If you’re at all interested in keeping your One X fully opened-up, this is not an update you’ll want to install; just wait patiently for devs to integrate these changes into their own ROMs.
