PureGear’s DualTek for iPhone 4 is shock and impact-resistant case for Apple's latest. It's sort of a cross between a bumper and a full-on case.

It offers reasonably rugged protection around the outside of your phone and claims impact protection from drops of up to five feet. You'll forgive us if we don't independently verify this claim...
