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 didnt. Sorry if this is old news to everyone. -Paul
I have a DLO FM transmitter in my car that doesn't work with the iPhone. I was bummed. It gives me that error, then it plays the music over the iPhones internal speakers... not the stereo. I hope someone gets something on the market soon to allow me to play music in my car.
