"I should also note that in the center of the D-Pad is a circular white lighting system that shows the phone status. When a call comes in, you get a rapidly blinking circle of light. When charging it will glow from bottom to top (and stay fully lit when charge is complete), and the top and bottom part of the ring flashes twice when there is a new message."
This is what is mentioned about the lighting on the dpad for the GSM touch pro.. wonder if the CDMA diamond has the same "feature".

REF: Looks like the GSM Diamond has this.
