Yes but I don't want my iPhone sitting in direct sunlight... It seems that it could damage the internals as well as fade the material. And please, don't reply "you don't have to use it"... I know this... I'm just saying.
A friend of mine pointed that out to (he mentioned the patent to me). Apple would most likely not use this on a phone. I agreed because then you'd have idiots leaving it in direct sunlight (in their car on their dashboard, but with their windows closed so nobody steals it) to recharge it and then going back to Apple with warranty claims.
Ture and not true. I'm sure there will be a "sensor" to denote misuse.
This will one day come to the iPhone, I just don't think the technology is quite there yet for the small size of the iPhone.
