Seidio iPhone 4 Convert Combo

Seidio's iPhone 4 Convert Combo (formerly called Rugged Combo) comes with a three-layered case, holster, and screen protector. In fact, the first layer is the Innocase Surface case, so you can strip the case down and go to thin protection when you want. This is why Seidio refers to it as a "convertible" case.

It's also worth noting that all the iPhone's ports are covered with flaps to protect from lint and dust (although the camera lens can be accessed easily enough when needed).
