Identical to the i-Mate JAM, the T-Mobile MDA Compact does exactly what it says on the tin - a compact MDA series smartphone running Windows, with a 240x320 pixel display in 65,000 colours, removable memory, Bluetooth and the powerful Windows Mobile operating system, all in an easy-to-handle package. The MDA Compact also has a 1.3 megapixel digital camera, rich multimedia playback and a wealth of software available.
