Helio has announced the launch of the Mysto for its Korean-language customers. This slider from Samsung shares the same design as the popular U600 for Europe. It will have a 2 megapixel camera, GPS, music player, Bluetooth, and a microSD memory card slot. The version available tomorrow will have Korean-language keypads and documentation. A regular English version of the Mysto will become generally available to all Helio customers in mid to late January. However, the Helio stores in Santa Monica, CA, and New York City will have a limited supply of the English versions of the Mysto available on December 26. The Mystos will not be displayed in the stores; Helio subscribers interested in a Mysto must ask to see one from behind the counter. The Mysto will sell for $149.
