At three ounces and 3.7 x 1.8 x 0.7 inches thick, the clamshell-style M500 is very light, compact, and comfortable to hold. The 
1.3-inch external screen sports 96 x 96 pixels and 65,000 colors, and the 1.9-inch internal screen provides 176 x 220 pixels and 262,000 colors. The handset doesn’t have media controls on the outside, so you have to open the phone for media playback.
It’s equipped with a 1.3-megapixel camera, 50MB of available memory, a microSD Card slot, stereo Bluetooth, earbuds, and a USB cable for PC synching and for using the phone as a modem (which requires a $39.99 monthly Power Vision plan from Sprint).
