AT&T has just launched yet another trendy 3G smartphone with advanced touchscreen capabilities. Called the Samsung Epix, the new enterprise-class handset will be exclusively available in the United States through AT&T, just like Apple's iPhone 3G.

"The Samsung Epix provides AT&T customers with the choice of the cutting-edge capabilities of a touchscreen and optical mouse combined with the convenience of a QWERTY keyboard," said Michael Woodward, a vice president at AT&T's wireless unit.
