Brodit have released a range of iPhone4 specific cradles.
The range includes active (powered) and passive (unpowered) designs, cradles that can accommodate a case (not Apple Bumper type) and a specific version designed to accommodate the iPhone4 with the Apple Bumper.
It seems that the deeply recessed sync port has precluded the option of an active cradle that can accommodate an iPhone4 fitted with Apple's official bumper wrap but this does still permit the direct connection of a suitable charge lead.
With some careful trimming of the shroud around the sync plug on the Brodit 3G/3GS cradle, I have made it work successfully with my iPhone4 which is fitted with the bumper.

I've stopped using my Apple Bumper because I found it was damaging the phone. Try removing the bumper and see if you have any shiny spots or lines on the matte metal surround. I'd be interested to know if others also have this problem.

OT for this thread but I have not seen any such marks on mine and I remove my bumper when I use it in the armband case at the gym.
