Query: Not for iPhone 3GS

I am sure this works great for ipods, but it does not work for the new iPhone 3GS. I hooked it up to my home stereo and no sound. After I jiggled the connection for a bit it worked, but who wants to do that each time. Also, the plug will not attach to the iPhone if you have a protective case because the plug it too fat. Of course your charger plug works fine because it is thinner. Now I need to find out if the mini will work.
