Quick: what phone form factor was conspicuously missing from Cingular's lineup? An ultra-thin slider, that's what. Enter the SGH-D807, Samsung's thin slider du jour, coming in at a trim .61 inches thick. Essentially an Americanized D800 minus the glorious QVGA screen, the D807 sports a more pedestrian 176 x 220 display, quad-band GSM, EDGE, a MicroSD slot, and the obligatory 1.3 megapixel camera. Available now for $129.99 after rebate with a new contract.
