The Samsung SPH-i550 smartphone is the Palm OS-based successor to the clamshell style SPH-i500.
A built-in MP3 player is controlled by external buttons without having to open the phone.
A unique feature of the i550 is that all programs and data are stored in non-volatile flash memory so that a hard reset of the Palm device will not cause information loss.
Just weeks after Sprint canceled the phone, it was announced that the SCH-i539, a Palm OS-based smartphone by Samsung that is very similar to the i550, was available in China.
Evidence on the Samsung Website indicates that a carrier in Mexico is in trials with the i550.
