Another day, another new sliding mobile phone. This time around AT&T and Samsung are teaming to reveal the Samsung SGH-a737, a slim and multi-color handset which will price at around $50 after your usual contract and rebate.

AT&T describes the SGH-a737 as “ultra-thin” and “entertainment accelerated.” What you’ve basically got here is a lightweight slider-style phone available in four color combos: black/orange, black/blue, black/red and black/lime. It’s got a lot of your typical bells and whistles, including a 1.3-megapixel digital camera, external microSD memory expansion and stereo Bluetooth 2.0 technology.

You’ve also got support for some AT&T specific features, including Video Share for one-way live video while on a voice call and Mobile Music for using your handset as a music player. Expect to get down with the SGH-a737 starting today.
