When I looked at how quickly it accumulates dust in the Dock plugs I looked around even after a dust cover. Is always difficult to detect whether the portions are also suitable for the bumpers. This is at least. Difficult was for me to realize how around the dust cover is inserted. As he calls the "| _ |" Form. However, you can see it quite quickly when the "board" look at. The dust was bent slightly at my house on, but thanks to rubber, I could turn something "straight" again. The plug fits into the "Dock". However, not for Bumper.
He does not complete with the Bumper on, but for me that is now no drama, the main cause of dust comes not so into it. Not pretty but functional! ;-)
The protection is also good out of the quick and poke in.
The only strange thing ... With me on the bill "iPhone 3 / 3GS Dust" was. From the 4 there was no question ... Where the Dock Connector to my knowledge are the same so all ... Perhaps there is some point even a special version Bumper who then also closes it.
