Let me make this clear: if you have perfect eyesight, then at one foot away the iPhone 4′s pixels are resolved. The picture will look pixellated. If you have average eyesight, the picture will look just fine.
So in a sense, both Jobs and Soneira are correct. At the very worst, you could claim Jobs exaggerated; his claim is not true if you have perfect vision. But for a lot of people, I would even say most people, you’ll never tell the difference. And if you hold the phone a few inches farther away it’ll look better.

"If you have bad eyesight you won't tell the difference" isn't a very convincing argument.

I don't think that that would matter. The problem would be one of receptor density:
Thus, both data sets indicate that myopic eyes have lower retinal resolution acuity than emmetropic eyes.
