The TIM update changes how the backlight works. It allows you to turn off the automatic backlight. The automatic backlight controls the keypad and white trackball light. If the keypad and trackball light are on it washes out the color. Try with autobacklight on and with it off and choose your favorite. I went ahead and put the very small piece of electrical tape on the white LED under the pearl and leave the autobacklight on. This allows me to have the extra bright mode for in the sun yet have the nice colored trackball when it's under dim light.
