We've already seen some pretty good iPhone 4 KIRFs, but it looks like there's a new king in town: the Air Phone NO. 4. Not only does it faithfully emulate the iPhone 4's hardware design with what we can only assume is the highest quality materials (it even eliminates those pesky seams), but it packs a "non-smartphone OS" that has all your favorite apps including Safari, Mail, "Games," "Sound" and, last but not least, FaceTime -- or a FaceTime icon, at least. Curious to see what other wonders await behind that familiar veneer? Then you can apparently snag one of these in China right now for just $100.
