Though we knew it was in the works, T-Mobile today officially announced the availability of Nokia’s Xpress Music 5610. The 5610 offers upgraded features from the previously announced Xpress Music 5310, including: a 3.2-megapixel autofocus camera with dual-LED flash, quick access to music function buttons, a microSD slot (with 1GB bundled in the box), stereo Bluetooth and a 2.2-inch QVGA display. Though the 5610 doesn’t support 3G, it is a quadband world phone.

The 5610 comes in white with silver trim or black with red trim for $99 and a two-year contract.
