Two different companies on opposite ends of the world have come up with distinctive cases for the iPhone 4 that reflect each company's values. Slovenia-based Calypso Crystal has launched a line of premium, hand-crafted luxury cases for three iPhone models and select other devices that features Italian leather, titanium and silver for elegance and style. San Diego-based LifeProof has focused on protection, with a case that claims to be water-, snow-, dust- and shock-proof.
