Waterproof Case for Iphone 3G.

I have looked and am trying to find a waterproof case for my Iphone3g that allows for taking photo's as well. Does anyone know of one? I looked at the H2O website and theirs looks like it is only good for listening to ipod application.

Also, if any Apple people are reading this, on the next version of Iphone, it would be cool if you made a waterproof one, even if you had to pay $100 or more extra for it.
