The HTC 8X on T-Mobile is set to receive its 'Portico' update starting tomorrow, December 19th. The update info comes via T-Mobile’s own support forums and will include an OS as well as firmware updates, bringing both up to OS 10211 and firmware version 1532.20.20004.531. T-Mobile is also emailing customers to let them know about the update, which is a nice touch.

The update for the HTC 8X will bring many new features, including stability (no random reboots or freezes), SMS call reject, the ability to mass select SMS messages and more under the hood optimizations including a reported great increase in battery life.

Microsoft so far has been quiet on the exact nature of this update, not providing an official changlog of the additions. T-Mobile US will be the first carrier to officially support and push out the OS bump to their customers, though AT&T and Verizon are expected to follow within the coming weeks (or sooner). The update should go a long way in making the 8X an even better phone than it already is, including the addition of a few bonus features.
