RIM announces the BlackBerry Curve smartphone also known as BlackBerry 8300.

The BlackBerry Curve features a silver finish, chrome highlights, smooth edges and soft curves. When I saw that name Curve, i was anticipating more dramatic curves, like found on the MOTORIZR Z8. Still, the Curve provides some nice improvements over the Blackberry Pearl.

The 8300 is a full-featured smartphone with a full QWERTY keyboard and a QVGA display.
The measurements are 4.2'' x 2.4'' x 0.6'' and the weight is approx. 3.9 oz. The screen of the Curve includes RIM's light sensing technology that automatically adjusts backlighting levels for indoor, outdoor and dark environments.
The BlackBerry Curve comes with a 2MP camera, complete with 5x digital zoom, built-in flash, self-portrait mirror and full screen viewfinder.

RIM integrated a standard 3.5 mm stereo jack in the new Blackberry 8300 to let customers connect any headset of their choice.
The BlackBerry Curve comes with a microSD expansion slot. It supports up to 2GB cards that are available today and will automatically support 4GB cards that are expected to become available later this year.

The Blackberry Curve comes with the Roxio Media Manager for BlackBerry, which was developed with Sonic and based on the award-winning Roxio Easy Media Creator 9, allowing users to search for media files on their computer, view and organize them, create MP3 music files from CDs, add audio tags, create playlists and automatically copy or convert pictures, music and videos for playback on the BlackBerry Curve.

The BlackBerry Curve (model number: 8300) will be available through wireless carriers around the world, including AT&T in the U.S., beginning this spring.
