I've never had any issue using my iPhone in sunlight. Granted, I live in London, where bright sunlight is like a rare delicacy, even in the summer (glances out the window... yeah..), but still, the point remains - I have never had any trouble reading my iPhone even with direct sunlight on it.

People love to keep saying that, but it's horseshit. The iPhone screen is perfectly usable in the brightest sunlight if you crank up the brightness to the max.
