iPhone 4S as a streaming client

Thanks, yes I've tried 8player - I can't get album art to work and really don't like the interface but had planned to use it as a last resort. And I'm also thinking of getting a logitech Radio so would prefer one system of linking them all together and I'm also interested in trying to figure out how to get this set-up to work if possible. As I said above if I can't, then I'll probably use a DNLA client.
