When you connect iPhone or iPod touch to your computer, items are automatically synced between the two according to your preferences. 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 touch screen to call.

You can sync

• Contacts—names, phone numbers, addresses, email addresses, and so on
• Calendars—appointments and events
• Email account settings (only on iPhone)
• Web bookmarks
• Music and audiobooks
• Movies
• TV shows
• Podcasts
• Photos

You only have 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, 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! Address Book (Except yahoo.co.jp accounts).

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.

Setting Up Syncing:

You use iTunes on your computer to set up which items are synced. Make sure you have the most recent version of iTunes (On a PC, open iTunes and choose Help > Check for Updates. On a Mac, open iTunes and choose iTunes > Check for Updates.
