bluetooth icon in menu bar, how to remove?

I have a Ti 500 PB. I exchanged HD's with my son's Al PB for a while (long story). Well we exchanged HD's back and now I have the bluetooth icon in the menu bar. How do I remove it since in system preferences there is no bluetooth preference to set it up? This PB does not have bluetooth. I am sure there is a terminal command to do this, I didn't see anything in CockTail.
