The Samsung Jet is an almost smartphone with a strong processor (800Mhz) and a large 3.1" touch AMOLED display. But the OS is Samsung's TouchWiz 2.0 (it's not a smartphone). Other features include a 5mp camera, an internal browser and DivX support. Here's a clip showing video playback on the Jet.
The Jet is available unlocked in the US for $400.
