Can I use my iPhone 5 case with the iPhone 5s?

The iPhone 5 and iPhone 5s share the same form factor and button placement, however there are design changes that could prevent an iPhone 5 case from being used on an iPhone 5s.

Most notably, the camera and LED flash on the back of the iPhone 5s are different from the previous model. Depending on how your existing case fits around the camera, it could prevent the iPhone 5s camera from operating correctly.
