I have a Case-mate iPhone 3G / 3GS case for sale. It's the White glossy barely there ine.
It's an Impact resistant shell and includes screen protection kit. NB I've just put a Case-mate screen protector on my phone and it was the best one I've used so far, with no air bubble and very easy to apply.
Brand new, boxed and never been used. Same as the one in first post
