Samsung's SCH-S310, introduced in 2005, has a three-axis accelerometer and three-axis magnetic sensor that give it a range of motion-detection capabilities. The company claims the phone can detect motion in three dimensions, as well as detect the speed of movements.
One of the S310's coolest tricks is letting users "write" numbers in the air that the phone can then dial. The phone, which is not sold in the U.S., also features a 1.3-megapixel camera, GPS and an integrated music player.
