I wrote an extremely short tutorial on how to automatically generate a BridgeSupport file for your Framework Xcode project: http://merbist.com/2011/02/19/bridgesupport-build/
Hopefully that will save some people the headache to figure it out on their own (not that it's hard tho).

One thing I didn't mention because it seemed very obvious... you need to have your target set to copy the headers to the final product.
