don't know, i've never checked into it. it does say in the directions to be sure you place the right cover on the dock when you get it. surely there has to be a way it comes off, because someone out there has probably put the wrong one on before.
That was something I thought of too... Nope nothing in the directions, I even called Apple, and they don't know.... But someone on here had said they did it, so.... hopefully someone knows.
