yes, i use the Inno Dock Jr. (from seidio). or there is also the original Inno Dock.
both are available from tipb store.
i dont have any posts here yet so i cant put up a link for you, so u should search it.
the dock connector is not permanently fixed onto the base, it rocks forward and back.
after you connect your iphone it leans back to rest on the back of the dock
im sure its been covered here before and you can also search youtube for reviews
