Samsung SPH-i500

The SPH-i500 is a Palm OS-based smartphone manufactured by Samsung. It was released in the Summer of 2003, with Sprint providing service in the United States.

The CDMA phone has a clamshell-style design, with the 160x240 pixel color display on the top half, and the Graffiti area and telephone keypad on the bottom half. It operates like a standard color Palm Pilot, but several hard and soft buttons launch the 'phone' application, which manages calls. Once a call is connected, it is possible to switch back to another application.
