Samsung Gravity, the black one in the image is their first to feature a slide-out keyboard that has proved popular in other brands. Samsung Gravity is a simple messaging phone with a well-designed QWERTY keyboard, a 1.3-megapixel camera, a music player, and a microSD card slot. Unfortunately, it may have disappointing call quality from time to time. In terms of Samsung Behold, the pink phone in the image, I think it offers superior image quality over the Apple iPhone 3G and the BlackBerry Storm.
