After long last the successor to Pantech’s popular Duo handset (AT&T) has finally shown it’s face.

The new Pantech Matrix PRO features HSDPA (up from UMTS), integrated GPS with AT&T Navigator, Bluetooth, a 2 megapixel cam, Video Share support, and Windows Mobile 6.1 Standard. It’s a bit big — 23mm thick — but here’s why: Dual keyboard sliding ability — one with a QWERTY, one with a number pad. At nearly 23mm thick, it’s not the thinnest smartphone in the world — that honor supposedly belongs to the Nokia E55.

The Pantech Matrix PRO’s prices and availability are unknown but stay tuned!
