Ready for another plain EDGE slider on T-Mobile? Well, there seems to be a “secret” 3G band buried deep inside, but for now, it’s all EDGE! T-Mobile just launched the Samsung t819, and the specs are pretty mid-range. Its got Bluetooth, a 1.3 megapixel camera, MyFaves support, T-Mobile Address Book support, microSD slot, and a pretty small 220 x 176 display. The “coffee brown” t819 should be available from T-Mobile directly and T-Mobile stores starting today.
