I appreciate the experiment, though. But one thing about the image quality: those lenses are specified assuming a 35mm (or 35mm/1.6) sensor. The sensor on an iphone must be 3.5mm at most, so the point spread function of the lenses aren't really matched to the sensor. I suspect that's part of why the quality is bad.
In other words, I cannot stop screaming "why?" while admiring his work.
