I'm not sure I understand. I was thinking of a small device that attaches to the iPod port where I can insert a small memory card that holds 8/16/32G more movies/shows/etc, all accessible from the iPhone like its own internal storage. This sounds a lot better than hooking up to a laptop. Or did you mean for transferring data to the iPhone?
