4.12 Joining and Separating Contacts
You may have duplicate contacts if you import contacts by:
•Adding an account, such as a Gmail account.
•Using the social networking services such as Facebook or Twitter. (If your phone has the Streams function, you can use it to access Facebook or Twitter.)
•Using other methods, such as exchanging emails.
To avoid duplication, join two or more contacts together to form a single contact.
Availability of Facebook or Twitter may vary depending on your country or carrier. Please use them according to local laws and regulations.
