RedHeep said he has one as well. Based on his recommendation and link a while back, I bought one when I bought my iPhone last weekend. That, plus the claim that they are dust proof, which given what we do was more important to me than being waterproof. I haven't had to put it to use yet but I look at it as more as an insurance policy. It fits well, appears to be constructed well, I think it's worth the money to not have to deal with a broken speaker and dusty screen like my BlackBerry had for the last 2 years.
Rated for drops on every edge and surface from 6.6' and waterproof to 6.6'... they are certainly designed to some fairly rigorous standards. Paid $80 for mine, not sure what Amazon has them for.
