Summer, is your Pearl from Verizon? The ColorPearl software will NOT work on your device if so. It is for the 8100 only - Verizon's Pearl model is 8130.
that what i was pointing out as well. if you are verizon, they have XX30 devices and the 8100 was the only one that had the multicolor LED's for the trackball.... its a bummer they took them out tho
