The combination of metals, such as aircraft-grade aluminium, with new advances, such as an internal antenna and a chemically etched keypad, led to the formation of a device that measures just 13.9mm thin. The RAZR V3 is possibly one of the thinnest clamshells to enter production. Couple this with the functionality you'd expect on a top-end phone and Motorola seems to have a winner on its hands. It also offers a 2.2 hi-res colour screen, 3D graphics engine, Bluetooth functionality, and precision cut keypad with electro luminescent cool blue backlighting.
