This article gives an overview of how to set up iPhone or iPod touch to sync with your computer, and where to get additional information.
When you connect iPhone or iPod touch to your computer, items are automatically synced according to your preferences set in iTunes. You can, for example, enter phone numbers and addresses of friends and family members on your computer, connect iPhone or iPod touch to sync, then unplug iPhone or iPod touch and tap a friend’s name on the touchscreen to call.
You can sync
Contacts—names, phone numbers, addresses, email addresses, and so on
Calendars—appointments and events
Notes (sync with Mac OS X Mail or Microsoft Outlook)*
Music and audiobooks
Movies and TV shows
Ringtones (iPhone only)
iTunes U content
* Syncing is over USB only and on a Mac requires Mac OS X 10.5.7 or later.
You only need to set which items are synced in iTunes on your computer once. After that, just connect iPhone or iPod touch to start a sync.
Contacts, calendars, notes, and bookmarks are synced from (or to) your computer, so if you add, change, or delete them on iPhone or iPod touch, they are changed on your computer, and vice versa. You can also sync contacts with your Yahoo! or Google Address Book.
Email account settings (on iPhone only), music, movies, TV shows, podcasts, and photos are synced one-way, from your computer to iPhone (though you can import photos taken with iPhone to your computer).
If you like, you can set iPhone or iPod touch 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 you may want to sync only songs from certain playlists so you don’t fill up iPhone or iPod touch with all your music.
