AT&T this morning added the Pantech Matrix Pro to its cellphone roster. The phone upgrades the design with a smaller but more upscale body that adds a larger 2.4-inch display and better materials. It also gets a full smartphone-class operating system and uses Windows Mobile 6.1 instead of the feature phone OS of the original Matrix; the switch gives support for full third-party apps and editing Office documents.

Also new in the Matrix Pro are conspicuous additions like a sharper 2-megapixel camera and data-assisted GPS mapping. More memory and a faster processor underneath also let it handle more tasks even with the overhead of the new mobile OS. It continues to support 3G on AT&T's network and has support for one-way Video Share calls as well as music and video streaming.

AT&T plans for the Pantech phone to be ready on February 24th, when it will sell for $180 with a contract and a $50 rebate.
