Sync your phone contacts with your Outlook (Outlook XP, Outlook 2003 or Outlook 2007), Outlook Express, or Windows Contacts.
If you have contacts to sync from your SIM card, you have to import these first to your phone storage.
On the Device panel, click People, and then click the On button.
Turning People sync on means you want this category included every time you sync your computer and phone.
Choose the application you want to sync your contacts with.
In cases when conflicting information is found on both the phone and computer, choose which information you want to keep.
Note: Only the contact fields supported on your phone will be synchronized.
