Wow Junko - what an interesting comparison of the two images. The iPhone image is nearly identical. It does look just a little more "artificial" maybe? It would be interesting to see them cropped to the same size - I think the "real" one may have a better overall feel to it then. :)
Comparing the two, I'd have to agree with @jgpittenger about detail and colour, and I'd have to prefer this one. That said, the iPhone shot is very good.
