I just don't get Syncing. Ever since I got my first iPhone I've had problems getting my Contacts and Mail on my phone to match what appears in Mail and Contacts on my Mac. I thought iCloud would sort this out but all it does is create duplicate copies of all my contacts on my Mac, so I keep iCloud turned off. Currently using iOS7 and OS10.8.5. I would be grateful if someone could talk me through setting my phone up to duplicate my Mac's info. Right now, when I try to Sync in iTunes it says "iTunes could not sync mail accounts to the iPhone because the mail accounts are in use by the phone". (It says this even when I disable the phone's mail accounts.) My Contacts don't match those on my Mac either. I'm at a complete loss as to how this is supposed to work. Can't understand why it's so difficult.
