On Wednesday, Marware launched a new protective case for its line of iPhone 3G/3GS accessories, the SportShell. The hard-shell case features an interchangeable design that enables users to alter the backing in three different ways. The first option is a 360-degree ratchet clip that attaches the iPhone to a strap or belt, and can also be locked into place to double as a stand. Next, users can just remove the clip and keep a thin back piece in place instead, or remove it altogether for an open-backed look that displays the phone’s Apple logo while still keeping it protected.

In additional to the changeable backing, users also receive a clear screen protector and cleaning cloth in the package. The SportShell comes with a lifetime warranty through the company and can be purchased directly from their online website for $35.
