Hi, I am getting an iPhone 3GS (sometime between Friday and Tuesday hopefully). Given what comes in the box with the iPhone 3GS, what do I need to buy to accomplish the following setup? * I want to have a dock at my computer. I also want a dock in my living room such that I can dock the iPhone and connect the iPhone to a set of speakers (computer speakers for example). * Here is where I think I am starting at so far: Buying 2 of these: http://cgi.ebay.com/Apple-iPhone-3G...6:4|39:1|72:1205|240:1318|301:1|293:1|294:200 But, after that I am not sure what extra cables/AC Adapters/etc I need to buy/have to get my setup working. All the research has made me glassy eyed Thanks!
