Apple has traditionally left cases up to third party developers. We have only seen a couple including a leather iPod case that was so expensive very few bought it, and more recently the iPad case. Today, during the WWDC keynote, Apple announced that they will be selling a new dock for the iPhone 4 and a case called the “bumper” as well. The bumper covers the perimeter of the iPhone theoretically providing a level of protection for the front and back by keeping a bevel around it. 
Additionally Apple announced a new iPhone dock for the iPhone, which would be expected with the new form factor.
