AT&T and Samsung have announced the Samsung SGH-a657, a rugged push-to-talk candybar phone. This quad-band GSM (850/900/1800/1900 MHz) device also supports UMTS (850/1900MHz) with HSDPA for high-speed data connectivity.
Certified to meet military specifications for dust, shock, vibration, altitude and temperature extremes, along with strong weather conditions like rain and humidity, the SGH-a657 can take a beating. Its rubberized handle makes the device easy to grip and a built-in flashlight will keep things illuminated in the dark.
With 128MB of internal memory, and expandable microSD card support, users can bring their favorite songs along with them and listen with Bluetooth A2DP-supported stereo headsets. The SGH-a657 also comes packaged with AT&T Navigator for on-the-go directions and AT&T Mobile Music for music lovers.
