Steps to Sync iPhone to New Computer

When you connect iPhone 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 to sync, then unplug iPhone 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 - Syncing is over USB only and on a Mac requires Mac OS X 10.5.7 or later)
• Web bookmarks
• Music and audiobooks
• Photos
• Podcasts
• Movies and TV shows
• Applications
• Ringtones (iPhone only)
• iTunes U content

You only need to set which items are synced in iTunes on your computer once. After that, just connect iPhone 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, 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 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 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.)

Step 1: Connect iPhone

Step 2: Set Up Which Items Are Synced

Click the respective tabs in iTunes to specify which media and information you want synced from your computer to iPhone.

Step 3: Sync iPhone

Click Apply in the lower-right corner of the screen. Your computer syncs with iPhone according to your settings.

The first time you sync iPhone, you are asked if you want to merge data, replace data on the service, or replace the data on your computer. After that, anytime you connect iPhone to your computer, iTunes opens and syncs with iPhone according to your settings.

You can adjust sync settings anytime iPhone is connected to your computer. You can only connect and sync with one iPhone at the same time. If you need to sync more than one iPhone, disconnect one before connecting the other.

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 online and delete the contact using Yahoo! Address Book.
