We have a Samsung HT-C550 Surround Sound system hooked up to our TV currently via an HDMI cable. It came with a dock for iPhone, which is really cool; however, as far as I can tell, you can only access your iTunes library to play through the system using the dock. I don't use iTunes for music. I have Napster (soon to be Rhapsody) and I use Pandora regularly. What I want to do is play my non-iTunes music (so basically any iPhone sounds) through the surround sound system. Can anyone recommend what I need to make this happen? What type of cables, docks, adapters, etc.? Probably need to also be able to charge while playing as well. Thanks!
