Joining contact information makes sending messages easy. You can
select any account email address or information all from one screen,
versus searching multiple, individual screens to locate the desired
account information.
Next time you synchronize your phone with your accounts, any
updates contacts make to email account names, email addresses,
etc. automatically update in your contacts list.
1. From the Home screen, tap .
2. Tap a contact name (the name you want to link to another
entry) to reveal the Contact entry’s Overview Screen.
Note: Typically this is the same contact with a different name or
account information.
3. Press and then tap Join contact.
4. Tap the second contact entry (the entry in which to link). The
second contact is now linked with the first and the account
information is merged into one screen.
Note: The information is still maintained in both entries, but displays
in one record for easier viewing when you link the contacts.
