How to make BlackBerry 8100’s light flash different colours. you can download a free flashlight app for your BlackBerry Pearl 8100. The app has like 6 or 7 different light settings, pink, blue, purple etc. The little light on the top right of my BlackBerry changes colours accordingly. you can make your phone flash those colours when you receive messages, mms,etc. The option only ever existed on the BlackBerry 8100 to make the trackball flash different colours.
