No, the lightwedge and case does not work with the 600. You can see a picture I took of the 600 in the lightwedge case by clicking
here, near the bottom of the page.
Someone, sorry don't remember who, said he had taken the lightwedge out of the case and used rubber bands to hold it in place over the screen of the 600. I haven't seen any picture of how he did that.
And by the way, you do know the lights in the lightwedge are LEDs?
