I guess you can't trump skills.

As for the iPhone. There's no doubt in my mind that more pixels on the camera is the least of it's worries. For starters, the iPhone's bane is low light, the image gets very grainy very fast.
Next I don't think the camera even resolves it's current 8MPix. Even when in good light, the image is a bit blurry and noisy when looking at 100%. That's doesn't really matter as no one looks at pictures at 100% other than if you print them huge. But it still tells us that there would be little gain with more pixels, I don't think the lens resolves it anyhow.
Lastly, the dynamic range of the camera is pretty bad. In other words, if there's a big difference between the dark and light parts of the image, it will the image starts loosing detail. IE, an indoor shot with a window on a bright day will show up completely white rather than show you some detail of the outdoors.
Better lens, larger sensor, better noise capability on the sensor, image stabilization should be prioritized. 8MPix is plenty from what I see people do with the images from their phones.
Yeah saw the vid already, that's where I got the idea to post that camera lol
