Got a Blackberry with a trackball and a Sharpie pen? If you do, you can change the color of that trackball according to one user at the Blackberry Forums. Blackberry Forums user SanFrancisco who calls himself a "Blackberry Genius," has posted a picture tutorial on how to take out the trackball and color the LED that lights it up. It looks like you'll need a small screwdriver, some alcohol, compressed air and your desired color of Sharpie pen. Once done, your trackball will light up to the color of your choice.

We're pretty sure this will void any warranty you have on the phone, but it sure looks cool!
