Samsung used this year's 3GSM World Congress to announce a large array of new phones. Three good examples are the U100, U300, and U700. The first is a ultra-thin style device, the second a clamshell, and the third a slider. All of them come with a 3 megapixel camera, high speed connectivity and everything you would expect from a cell phone these days. The U100 has been called the thinnest phone currently available at 5.9mm thickness.

“The new Ultra range is set to become the ultimate standard-bearer for Samsung's mobile products by combining form, function and fun,” said Geesung Choi, President of Samsung's Telecommunication Network Business. “These multimedia driven handsets are designed for consumers who wish to stand out from the crowd, showcasing unrivaled performance, advanced functionality and world-class design.”

These models look just great, but what really caught my attention was the F700, which has been dubbed by some an iPhone “killer”. It comes with 5MP built-in camera, GSM, EGDE and 3G compatibility, a 2.78” touch-screen, and fully-featured QWERTY keyboard. The device looks small enough, but the price tag is not. You can expect the high-end F700 to compete with the iPhone, though some think it might go for well over the $700 mark.
