Samsung released t739 Katalyst for T-Mobile. This phone features Hotspot@Home, 1.3 megapixel camera, 220×176 display and Bluetooth. t739 joined T-Mobile’s WiFi, being the first one certified for this enabled calling service. The Katalyst is a remake of the t409 with an upgrade consisting of a microSD slot. We were expecting a bit more from them but for now we are happy. You can get it on a two-year contract for $80.
