I think Samsung has an obsession with Ultra Slim Phones, that’s why the company comes with another slimmest DMB phone in the world. The new SCH-B510 measures just 8.4mm thick that makes it even slimmer. The handset also features a DMB TV tuner, an MP3 player, MicroSD slot, a 2MP digicam, Motion Detection, MS File Viewer, and 3D Messenger. No word on pricing or availability yet.
