AT&T has officially announced the launch of the Samsung a737 phone for their 3G network. The new slider device features HSDPA support, a 1.3 MP camera, A2DP stereo Bluetooth, video sharing support, and micro-SD functionality. The a737 will be available in lime, yellow, and orange, all with black accents. The cool thing about this phone is that it will be available for only $49.99 with the purchase of a 2-year contract. Not too shabby for a HSDPA-ready media phone. The AT&T Samsung a737 is available starting today.
