T-Mobile USA has launched yet another UMA phone for its T-Mobile @Home service: Samsung's t739 Katalyst. The carrier already offers the Nokia 6086 and the BlackBerry Curve 8320 for the fixed-mobile convergence service, but the Katalyst is the first slider phone it has offered for it. The phone also features a 1.3 megapixel camera, Bluetooth and a microSD slot. The phone will retail at $79.99 with a two-year contract.

Hotspot@Home, launched in June, allows T-Mobile customers to connect via the firm's cellular network and its 8,500 WiFi hotspot locations across the country.
