This program for the Pearl lets the colors cycle through. Its pretty neat, my friend with T-Mobile has it on his Pearl.

Does anyone know if unlocking the Curve will allow users to change the trackball color? or is it really a matter of the Curve not coming equipped with the hardware to do so?
By the way, this Blackberry is so amazing, I haven't put it down yet.
