These are features in the previous version of Yahoo! Go. We are planning to re-introduce these features in the next version.

Yahoo! Go 3.0 does not synchronize your device's address book with your Yahoo! Address Book.

However, you can use Yahoo! Go 3.0 to access your Yahoo! Address Book by pressing the green button, the phone call answer button, on your phone. You can also use Yahoo! Go 3.0 to access your Yahoo! Address Book and address your emails.
