Well I got board today and decided to go mess around with the several different models of iPod speaker docks. To my surprise, the iPhone worked on almost all of them. Mostly the JBL and altec lansing ones. I got an onscreen message on the iPhone that read something like "This iPhone accesory is not supported", but it still worked. Hopefully I can go again and get all the different model numbers of the ones that worked and didn't. Sorry if this is old news to everyone. -Paul
