The Japanese has come up with a really interesting iPhone case! It is the Factron Quattro for iPhone SP, a case made from leather, carbon fiber, and stainless steel. The case might sound expensive for slightly under $200, and may look a bit weird, but this case provides the ultimate in iPhone 3GS protection and at the same time offers extra lenses for iPhone’s camera function.
You can accessories this case with additional lenses such as the fish-eye, wide angle, and macro zoom which costs between $15-50 each. This case and the lenses look like really fun, don’t they? Certainly make your iPhone stands out!
Not sure if you could get this elsewhere other than Japan. Check out more on this Japanese site Factron.
