Helio today introduced a new slider-phone called "Mysto". It’s not an entirely new phone as it is based on the Samsung U600, which has been on the market for some time in Europe and Korea. The Mysto will sell for $150 and offer (free) GPS capability with Google Maps integration. For $3 per month, Helio offers Microsoft’s Tellme service, which enables users to search for local information via voice input.

The Mysto comes with a 2 megapixel camera, a 2.2" display, 100 MB of internal memory as well as a microSD expansion slot. The flat electrostatic keypad is equipped with Immersion’s TouchSense technology and provides haptic feedback, simulating the feel of a real physical key.
