If you happen to have a BlackBerry Pearl I suggest you take a tip from the Spice Girls (hey, they are hot again, right?) and "spice up your life." You can do so by downloading ColorPearl, which allows you to change the color of the trackball on your BlackBerry Pearl. You can get the download for free from Viral Electronics. An easy way to get the software on your Pearl is to email the downloadable attachment to yourself and open it on your BlackBerry.
Note: The BlackBerry 8800 and Curve/8300 do not have the colored LEDs behind the trackball, so there is no way to make ColorPearl work on them. You can change your Pearl to white, red, green, blue, cyan, yellow, pink, custom or random.
