i read somewhere that the quick and easy test is to take a shot, in a darkened room of the front of a TV remote... then do the same with you pressing one on of the buttons... compare the images and if you see a bright light coming from the IR LED then your camera is IR sensitive :)
I'm yet to discover if my 30d does this...

"In every colour, there's the light.
In every stone sleeps a crystal.
Remember the Shaman, when he used to say:
Man is the dream of the Dolphin"
