And not have everything merged and synced, is it? I'm trying to help someone out that has his and his wife's contacts calendars and so on merged and synced on both their phones. He's been using the same iCloud account on both phones with back up. He wants to separate them. I told him just to delete iCloud from his wife's phone and for her to create a new ID. Everything should now be separate but they can still share the same ID on the App Store. Now someone comes along and says he and his wife share the same iCloud account and nothing is merged and he has backup set to on. I can't see how that's possible.
