The Pantech C820 GSM smartphone has recently been spotted on the FCC site. The info on it just shows support for GSM and Bluetooth connectivity. The model number likely means that it will end up being the Duo 2 for AT&T. There is no way to know for sure as of now if it will end up being the Duo 2, but it’s a safe guess. The original Duo, the Pantech 810 Duo is a dual-slider smartphone that features a numeric pad as well as a slide-out QWERTY keyboard.
