Oh, and if you're into video, Apple has empowered the iPhone 4S with the ability to grab 1080p video. The video function will also use its own specific noise reduction system and a digital image stabilization system. But, don't get that confused with optical image stabilization. Because the video capture doesn't use the entire sensor, it has the ability to shift the frame to keep things steady. The lens elements don't move like they do in optical IS systems, so it won't work in still capture mode.
