Just got the dock and it DOES fit with the cover on (I use a Silicone Gel cover). There's a kind of spring arrangement where the phone sits that allows for this. A curious feature is that when you sit the phone on it, it changes the home screen but when you click the "X" at the top of the screen it changes back to your normal screen. It's quite well made and a nice solid piece of kit, plus it fits the Galaxy S2.
