Ballistic has announced that it is now shipping its Ballistic LS case for the iPhone 4. Previewed by iLounge in December 2010, the Ballistic LS is made from TPU material, and features four interchangeable silicone “Ballistic Corners,” which vary in color and thickness to allow for a customized level of drop protection, as well as push-through protection for the volume and sleep/wake buttons, compatibility with both GSM and CDMA models, and open access to all other ports, controls, and cameras. The Ballistic LS case for iPhone 4 is available now in translucent gray or translucent blue and sells for $30.
