The ProCable Shortz Extender from RadTech is a spacer adapter for Apple's 30-pin dock connector. We've seen a couple of these recently and the idea is to allow Apple's iOS devices to connect with various 30-pin cables and docks while in a case. For example, Apple's Bumper case has a fairly narrow opening and unless you're using the newest version of Apple's 30-pin cables, you're unlikely to make a solid connection. Apple's older and many third-party connectors are larger and may not fit into the 30-pin cut out. Other possibilities may allow iPhone, iPad, and iPod to dock with various accessories while inside of a case.
The ProCable Shortz Extender is available now for $19.95
