AT&T and Pantech have just introduced the Matrix, a dual-sliding handset with both a QWERTY keyboard and a regular number keypad, just like the Pantech Duo and the Helio Ocean (also made by Pantech). Unlike the Duo, the Matrix is not a smartphone, and is primarily designed as a messaging phone with high-end multimedia features. Its features include HSDPA, Bluetooth, a microSD card slot, A-GPS (with AT&T Navigator support), instant messaging, a music player, mobile e-mail, a 1.3-megapixel camera, and quad-band GSM support.
Since it's a 3G phone, the Matrix will also have access to AT&T Video Share calling, AT&T Mobile Music, Cellular Video, and mobile e-mail. The Matrix measures 4.02 inches by 1.97 inches by 0.78 inch and weighs about 4.7 ounces. It comes in red, green, and blue. It's officially available starting today, but some stores have already begun selling them. The Matrix will cost you $79.99 with a two-year service agreement, after a mail-in rebate.
