AT&T Debuts Smaller, Lighter BlackBerry

Research In Motion said Wednesday that it had launched its smallest and lightest BlackBerry yet through US carrier AT&T, which begins carrying the device on Thursday. The BlackBerry Curve features a full QWERTY keyboard and will be usable on AT&T's EDGE network. Other features include a 2-megapixel camera, microSD slot, and trackball navigation.

AT&T customers will also be able to use the carrier's Push to Talk functionality through the device, as well as access the company's music and navigation services. The Curve will be available for $199.99 after mail-in rebates and a two-year contract term. Data plans start at $29.99 per month, AT&T said.
