Pantech and AT&T have partnered up to launch the Pantech Duo today, available exclusively via AT&T. The new Windows Mobile 6 smartphone takes some design cues from its cousin, the Helio Ocean, with its dual-slider design. Yes, it sports both a slide-out number dialpad as well as a QWERTY keyboard. Features include quad-band support with HSDPA, access to AT&T's broadband services like Mobile Music and Cellular Video, stereo Bluetooth, and a 1.3-megapixel camera. It's currently available from AT&T for an introductory price of $199.99 with a two-year contract and a mail-in rebate. We currently have a unit in-house and are eager to put it through its paces, so stay tuned for our full review.
