Clarifi is a tough polycarbonate protective case from Griffin with built-in close-up lens for iPhone 3G.
iPhone requires about 18 inches to focus properly – slide Clarifi’s lens into place and you can move in to 4 inches. Perfect for imaging a business card full frame, for example.
I’ll wait for a review to know for sure, but right now this looks like the case for me :D I hope it lives up to my expectations.
