Syncing iPhone with Your Computer

When you connect iPhone to your computer, iTunes syncs iPhone with the information and media on your computer, according to how you’ve configured the iPhone sync settings in iTunes.
You can set iTunes to sync any or all of the following:  Contacts—names, phone numbers, addresses, email addresses, and so on  Calendars—appointments and events  Email account settings  Webpage bookmarks  Ringtones  Music and audiobooks  Photos  Podcasts  Videos
Ringtones, music, audiobooks, podcasts, and video content are synced from your iTunes library. If you don’t already have content in iTunes, the iTunes Store (available in some countries) makes it easy to purchase or subscribe to content and download it to iTunes. You can also add music to your iTunes library from your CDs. To learn about iTunes and the iTunes Store, open iTunes and choose Help > iTunes Help.
Contacts, calendars, webpage bookmarks, and photos are synced from applications on your computer, as described below. Contacts and calendars are synced both ways between your computer and iPhone. New entries or changes you make on iPhone are synced to your computer, and vice versa. Webpage bookmarks are also synced both ways.
Email account settings are only synced from your computer’s email application to iPhone. This allows you to customize your email accounts on iPhone without affecting email account settings on your computer.

If you like, you can set iPhone to sync with only a portion of what’s on your computer. For example, you might want to sync only a group of contacts from your address book, or only unwatched video podcasts. You can adjust sync settings whenever iPhone is connected to your computer.
Important: You can connect and sync with only one iPhone at a time. Disconnect one before connecting another. You should be logged in to your own user account on the computer before connecting iPhone. On a PC, if you sync more than one iPhone to the same user account, use the same sync settings for each.
Setting Up Syncing
You use the iPhone settings panes in iTunes to specify the iTunes content and other information you want to sync to iPhone.
Set up syncing
1 Connect iPhone to your computer, and open iTunes (if it doesn’t open automatically). Unless your keyboard has a high-powered USB 2.0 port, you must connect iPhone to a USB 2.0 port on your computer.
2 Select iPhone in the iTunes window (below Devices, on the left).
3 Configure the sync settings in each of the settings panes.
4 Click Apply in the lower-right corner of the screen.


Info Pane
The Info pane lets you configure the sync settings for your contacts, calendars, email accounts, and web browser.
Contacts
You can sync contacts with applications such as Mac OS X Address Book, Microsoft Entourage, and Yahoo! Address Book on a Mac, or with Yahoo! Address Book, Windows Address Book (Outlook Express), 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.
Note: Syncing won’t delete any contact in Yahoo! Address Book that contains a Messenger ID, even if you’ve deleted the contact from your address book on iPhone or your computer. To delete a contact containing a Messenger ID, log in to your Yahoo! account and delete the contact using Yahoo! Address Book online.
Calendars
You can sync calendars from applications such as iCal and Microsoft Entourage 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.)
