Specification :

Better display than the BlackBerry Bold. Hard to imagine, but true. The Javelin 8900 has a smaller screen but higher, 480 x 360 pixel resolution.
Improved camera over the Bold. A 3.2 MPx camera, with a class cover protecting the lens and flash Makes the Javelin perfect for shutterbugs.
Keypad resembles the BlackBerry 8700. The navigation buttons are also smaller than the Bold’s and you may be able to change the trackball color to gray or black.
Very different side layout. The right side of the BlackBerry Javelin features a headphone jack and Micro-USB controls in addition to volume controls and convenience key.
