As a first time iPhone purchaser, with the iPhone 5, I am very disappointed to find that there is no exposure compensation; this most elementary and fundamental photographic control. I understand that it's not even possible for any apps to do this due to the limitation of the SDK. Why? Full manual control of aperture, shutter speed and ISO is of course far too much to expect us moronic and incapable Apple customers to understand but we could at least be permitted to determine for ourselves if we are photographing a white rabbit in the snow or a black cat in a coal shed and overide the averaged metering to control exposure. And yet it is possible to retrospectively apply a panoply of ugly filters; urgh.
