Helio has gotten official with the slim, sexy Mysto slider -- a branded, CDMA rendition of the Ultra Edition 10.9 that should ultimately become the MVNO's top of the line handset just this side of the Ocean with a 2 megapixel camera, microSD expansion, and the now-typical GPS and EV-DO data. There's a catch, though; it turns out that Helio will start out by soft launching the phone through its "Helio powered by SK Telecom" division that caters directly to the Korean American market. A full-scale launch is planned for January, but we've been told that folks should be able to approach staffers at Helio's New York and Santa Monica stores with a nudge nudge, wink wink starting December 26 and get hooked up for $149 (even though no Mystos will be on display). Good luck, shoppers!
