Samsung and Sprint today introduced its second new cell phone of the week with the Samsung SPH-M300. Available in red and silver, the M300 offers a mostly low-end feature set, but it manages to throw in a couple of extras. Inside you'll find a VGA camera, Bluetooth, voice dialing, and a speakerphone. The flip phone design is very basic with a flat keypad and a small, color external display. And in keeping with Samsung's thin phone obsession, the M300 has a slim 0.7-inch profile. It's $29.99 with service.
