"Apple has added the ability for the sensor in the iPhone 5 to take pictures at 4 times the sensitivity. If you're a camera buff this means the ISO can go from a limit of 800 before, up to 3200 now!"
Camera was always too slow to use on my iPhone 4.Since upgrading to the iPhone 5 Camera has made its way onto my main Dock. I'm glad for this update.
One quibble, though, would be that I wish Camera would save its photos directly to my Camera Roll rather than to its own Library.
