Case-Mate has released their new Hula case for the iPhone 4. The Hula is very similar to Apple's Bumper case with one difference, it has a clear plastic middle to show off your iPhone 4's metal bezel in between the colored silicone frame. The Hula combines two materials, impact resistant silicone edges and a clear TPR plastic. With the Hula case you get a screen protector as well as a back protector to keep everything scratch-free. The Hula case is available right now in nine colors for $19.99.
