How to Sync Address Book Contacts with iPhone 4S

If you are using iCloud to sync contacts, DO NOT enable contacts in iTunes. You may miss the warning in fine print, so heed this warning in big type: IF YOU ENABLE SYNCING WITH iCLOUD AND ALSO ENABLE IT IN iTUNES, YOU MAY END UP WITH DUPLICATED DATA ON YOUR iPHONE. You won’t like that, so enable syncing one way or the other — via iCloud or in the iTunes Info pane.

The iPhone syncs with the following address book programs:

• Mac: Address Book and other address books that sync with Address Book, such as Microsoft Outlook 2011 or the now discontinued Microsoft Entourage
• PC: Windows Contacts (Vista and Windows 7), Windows Addressbook (XP), Microsoft Outlook, and Microsoft Outlook Express
• Mac and PC: Yahoo! Address Book and Google Contacts

Now, here’s what each option in the Sync Contacts section does:

• All Contacts: One method is to synchronize all your contacts, which is what the figure shows. This will synchronize every contact in your Mac or PC address book with your iPhone’s Contacts app.
• Selected Groups: You can synchronize any or all groups of contacts you’ve created in your computer’s address book program. Just select the appropriate check boxes in the Selected Groups list, and only those groups will be synchronized.
• Yahoo! or Google Contacts: If you use Yahoo! Address Book, select the Sync Yahoo! Address Book Contacts check box and then click the Configure button to enter your Yahoo! ID and password. If you use Google Contacts, select the Sync Google Contacts check box and then click the Configure button to enter your Google ID and password.
• If you use Yahoo!, note that syncing doesn’t delete a contact from your Yahoo! Address Book if the contact has a Yahoo! Messenger ID, even if you delete that contact on the iPhone or on your computer. To delete a contact that has a Yahoo! Messenger ID, log on to your Yahoo! account with a web browser and delete the contact in your Yahoo! Address Book.

If you sync with your employer’s Microsoft Exchange calendar and contacts, any personal contacts or calendars already on your iPhone will be wiped out.
