I love the design of Apple's bumper cases for the iPhone 4S, but they are too confining around the dock connector and only allow for the use of Apple's USB/docking cables. Third party cables that are thicker around the connector base won't work at all. This is the predicament I find myself in because the proprietary iPhone/iPod hookup in my Hyundai Sonata won't work with the standard bumper case without enlarging the opening (which I don't have the tools to do). I've tried at least three different "cheap" Chinese bumper cases from eBay but they have either been ill-fitting or just pure crap. So I'm looking for a good bumper case that offers a generous "open space" around the dock connector to allow for larger dock connectors. Any recommendations?
