This may seem like a stupid question for those of you who have an iphone. I have one ipod. Surely itunes will let you sync an iphone in addition to an ipod, right? Itunes downloads are playable on up to 5 computers - so I am assuming also up to 5 ipods/iphones? Does itunes create a different profile for each device? The itunes library has a check box next to each song indicating that you want to sync it to your ipod. If you have more than one device, how does this work?
