It comes out this summer! I just looked at the SXSW press release statement about it. I can't wait. I hope they have tactical colors, but it says it will have a clear back.
I have seen them on iphones as well. The lifeproof definitely seems to be thinner than the other waterproof case that I have seen for the S3. I am really hoping that it comes out before summer. Thanks sweeds. Hard to get many people to say Let's go STATE recently.
