so I have my super duper iphone and the kids are getting touches for xmas. I take it it's just a case of making playlists for each of them and syncing them but what about apps?? will each app I own be able to sync to 3 devices and will I be able to play games over bluetooth with them?? ie air hockey you can play over bluetooth but is it ok if both gamers are from the one itunes account meaning 2 copies of the same game? just trying to clear this up in plenty time?
