Automobile aficionados can put the pedal to the metal with the Case-Mate Vroom. A standard-looking, black silicone iPhone 3G/3GS case from the front, but the back features a tire-tread pattern reminiscent of speed-rated performance tires. All controls are accessible and a lip gives chrome bezel protection and a “lay on the table” design. Also available in a 1st Gen iPhone version in multiple colors. Test drive one for $14.99.
