OK, there may be a very easy fix for this, but I couldn't find it. Here is what I want to do - listen to Pandora (and other iPhone media) through my computer speakers. I want to charge my iPhone, sync my iPhone and send my iPhone's audio signal to my computer all via one device or cable. Is this possible? If so, how? Do I need to buy a speaker system? Can I do it with the (missing) dock for the iPhone 3G? Thanks.
