If you lose any of the chrome metal rails or panels on your Blackberry, they can be easily replaced with out of the box OEM parts from RIM. These parts are completely new and never fitted to any Blackberry, allowing you to simply pull your housing apart and replace them with relative ease.
Be sure to match the side panel buttons to the model of Blackberry you have as different models have different sizes and shapes of buttons. The Blackberry Pearl is represented on this page with four different model shapes and sizes.
