Both cameras--the front- and rear-facing ones--are updated on the iPhone 5. The networking--both wireless and cellular--is improved, with new LTE support and Bluetooth 4.0. The audio's better, and there's a new dock connector port called Lightning, too.

The rear-facing camera gets an update with a new dynamic low-light mode and sapphire lens cover, and leverages image processing technology new to the A6 chip. The front-facing camera gets an upgrade, too; it's now a FaceTime HD 720p HD camera.

The allows you to take photos while you're shooting video, which is a first for an iPhone. That sapphire lens cover should not only protect the lens, but also make images look cleaner and sharper, Apple claims. And, along with the iPhone 4S in iOS 6, the iPhone 5 offers a built-in option called Panorama, for taking stitched-together panoramic shots.
