Didn't they say the dimensions were from an 8mgp camera although it says iPhone4Exif data shows iPhone 4, taken 7/22/2011 location does center non the Apple headquarters. Too bad this data is kind of easy to tweak / fake.
but I'll go out a limb and say it's a real iPhone 5 photo.
If they made the Apple logo the lens it would do much better in low light. Don't know how much better they can actually get it from such a tiny lens.I would like to see better lens and better picture quality in low light conditions, compared to more megapixels. It would be great if there is both though.
