The Curve 8900, also known as the BlackBerry Javelin, has made waves since late last year, sparking a heated debate whether T-Mobile or AT&T would be the first to offer the quad-band handheld. While T-Mobile was first to the table with an official announcement last week, it appears AT&T will also soon be getting the device.

According to popular gadget blog the Boy Genius Report, BlackBerry maker Research In Motion showed off an AT&T-branded 8900 in its booth at CES 2009 in Las Vegas last week, putting to bed rumors that T-Mobile would be the only carrier to get its mitts on the coveted smartphone.

The mobile world originally thought AT&T might pass on the anticipated device, mainly because it lacked high-speed 3G connectivity.

It's still suspected that T-Mobile's BlackBerry Curve 8900 will hit the streets first, but AT&T won't be far behind, and will likely offer the smartphone as a non-3G alternative to the high-end BlackBerry Bold 9000.

The Curve 8900 is billed as the lightest and thinnest BlackBerry to feature a full QWERTY keyboard, clocking in at just over a half-inch thick. It also offers all of the features and functions BlackBerry users have grown accustomed to, including phone, e-mail, text messaging, browser, instant messaging, document viewing and editing, and organizer applications. It also ties in a host of multimedia functions, such as a media player.

The Curve 8900 offers EDGE support with built-in Wi-Fi and GPS, a 512MHz next-generation processor, a 2.4-inch 480 x 360 high-resolution display, a 3.2-megapixel camera and BlackBerry OS version 4.6.

The BlackBerry Curve 8900 has already launched in Canada and the U.K. In the U.S., the Federal Communications Commission approved the smartphone in November.

Neither carrier has discussed the exact release date for the BlackBerry Curve 8900 or released pricing.
