So far we’ve only heard from Verizon, but that doesn’t mean other carriers in the U.S. are sleeping. AT&T today announced the new Motorola’s music-centric slider Z9, which we previously saw leaked by the FCC. Specs include such things as a built-in GPS receiver, 3G radio, music player, microSD card slot (up to 8GB cards are supported), stereo Bluetooth, 2 megapixel camera, Opera 8 and of course the microSD memory card. As for the services supported, the Z9 can sing along AT&T Mobile Music, AT&T Navigator and Video Share. The device is already available for $249.99 after a two-year service agreement. AT&T’s official release is available from here.
