Sony Ericsson W810 has a "heartbeat illumination" feature?

The Right Phone, the Right Music

Looking for a true music experience? With its "heartbeat illumination" feature, the Sony Ericsson W810's control keys glow in rhythm with your music. Did we mention that it's marked down and--and unlocked?

The above is the blurb for the Sony Ericsson W810 over at Amazon's site. They seem to think that the W810 has this special feature. I think they are mixing this up with the W850 or is there some special new firmware that allows this? I certainly have not heard of this. This was found by a member over at howardforums. Nice find!
