The following sections provide an overview of each of the iPhone settings panes. For more information, open iTunes and choose Help > iTunes Help.
Select “Automatically sync when this iPhone is connected” to have iTunes sync iPhone automatically whenever you connect it to your computer. Deselect this option if you want to sync only by clicking the Sync button in iTunes. For more information about preventing automatic syncing, see Preventing Automatic Syncing.
Select “Sync only checked songs and videos” if you want iTunes to skip unchecked items in your iTunes library when syncing.
Select “Manually manage music and videos” to turn off automatic syncing in the Music and Video settings panes. See Manually Managing Content.
Select “Encrypt iPhone backup” if you want to encrypt the information stored on your computer when iTunes makes a backup. Encrypted backups are indicated by a padlock icon, and a password is required to restore the information to iPhone. See Creating Backups.
Click Configure Universal Access to turn on Accessibility features (available only on iPhone 3GS). See Accessibility.
The Info pane lets you configure the sync settings for your contacts, calendars, email accounts, and web browser.
Contacts
Sync contacts with applications such as Mac OS X Address Book, Yahoo! Address Book, and Google Contacts on a Mac, or with Yahoo! Address Book, Google Contacts, Windows Address Book (Outlook Express), Windows Vista Contacts, or Microsoft Outlook 2003 or 2007 on a PC. (On a Mac, you can sync contacts with multiple applications. On a PC, you can sync contacts with only one application at a time.)
If you sync with Yahoo! Address Book, you only need to click Configure to enter your new login information when you change your Yahoo! ID or password after you’ve set up syncing.
Calendars
Sync calendars from applications such as iCal on a Mac, or from Microsoft Outlook 2003 or 2007 on a PC. (On a Mac, you can sync calendars with multiple applications. On a PC, you can sync calendars with only one application at a time.)
Mail Accounts
Sync email account settings from Mail on a Mac, and from Microsoft Outlook 2003 or 2007 or Outlook Express on a PC. Account settings are transferred only from your computer to iPhone. Changes you make to an email account on iPhone don’t affect the account on your computer.
NOTE: The password for your Yahoo! email account isn’t saved on your computer, so it can’t be synced and must be entered on iPhone. In Settings, choose “Mail, Contacts, Calendars,” tap your Yahoo! account, and enter the password.
Web Browser
You can sync bookmarks on iPhone with Safari on a Mac, or with Safari or Microsoft Internet Explorer on a PC.
Notes
Sync notes in the Notes application on iPhone with notes in Mail on a Mac or with Microsoft Outlook 2003 or 2007 on a PC. (On a Mac, you must have Mac OS version 10.5.7 or later installed to sync notes.)
Advanced
These options let you replace the information on iPhone with the information on your computer during the next sync.
Use the Applications pane to specify which App Store applications to sync on iPhone, or to arrange your Home screen (requires iTunes 9 or later). Any applications downloaded directly to iPhone are automatically backed up to your iTunes library when you sync. If you manually delete an application on iPhone, you can reinstall it from this pane as long as it was previously synced.
Use the Ringtones pane to select the ringtones you want to sync to iPhone.
Use these panes to specify the media you want to sync. You can sync all music, movies, TV shows, podcasts, and iTunes U collections, or select the content you want on iPhone.
If you want to watch rented movies on iPhone, transfer them to iPhone using the Movies pane in iTunes.
If there’s not enough room on iPhone for all the media you’ve specified, iTunes can create a special playlist and set it to sync with iPhone.
NOTE: The iTunes U pane appears only in iTunes 9 or later. In earlier versions of iTunes, iTunes U content appeared in the Podcasts pane.
You can sync photos and videos (Mac only, iTunes 9 required) with iPhoto 4.0.3 or later, or Aperture on a Mac; or with Adobe Photoshop Elements 3.0 or later on a PC. You can also sync photos and videos in any folder on your computer that contains images.
