On: How much of an iPhone is made by Samsung?

This is pretty pointless, as final image quality depends on a lot more than just the sensor, especially on a phone, but a better measurement of sensor quality is pixel size or density, as bigger pixels gather more light.

Pixel density is calculated as a ratio of resolution to area, is usually expressed in MP/cm^2 and lower is better.

    iPhone 4: 5MP, 1/1.7", area 0.15cm^2, density 32MP/cm^2
    N8: 12MP, 1/1.83", area 0.38cm^2, density 31MP/cm^2

As for the lens, I prefer wide angles, but again the raw numbers don't tell you much.

So the N8 has the same pixel density, twice the amount of pixels, and the iPhone is the one with the really good CCD, got it.

I didn't say that.

Yup. computator did.
