We've known it was coming for a long time, but only Monday did T-Mobile come clean by announcing the Nokia 5610 Xpress Music. As the big brother to the previously released Nokia 5310 Xpress Music, the 5610 offers an upgraded and music-friendly feature set in a slider design with a brilliant display. Inside you'll find an Xpress Music player, a 3.2-megapixel camera, full Bluetooth with a stereo profile, an FM radio, a microSD card slot, USB mass storage, voice dialing, a speakerphone, and messaging and organizer applications. Unlike the original model, the T-Mobile 5610 doesn't support UMTS networks but it is a quad-band world phone. It is $99 with service and comes in black with red accents and white with silver accents. We'll have a full review on Tuesday.
