Today marks the official unveiling of the Samsung Beat (SGH-t539) on the T-mobile network. The Beat is a pint-sized flip phone dressed in a black shell with a silver keypad and lime green accents. The latest T-mo handset has dedicated external music controls, a stereo speaker, stereo Bluetooth and comes packed with a 1GB microSD card that’s pre-loaded with two tracks from Anisha Nicole and Natalie Williams. The 1.3-megapixel camera with 4x zoom actually takes decent pictures as well as capturing video. The Beat is compatible with T-mo’s myFaves and address book. Yeah, that’s about it. Look for a full review in the coming days, but hit the jump for more pics.
