Who bought a Bumper for iPhone 4G, is as foolish as the docks so far (July 2010) do not work, the Bumper does not allow connection or it does not fit purely. As Griffin helps. This adapter allows the iPhone to "float", so that the contacts are made. Too bad that Apple did not think of their own Bumper when they designed their docks ... Therefore prefer to continue using the old dock, as the new iPhone 4 Dock buy, instead, this Converter Buy.
