When restoring the address book, Backup Assistant compares and merges any contact information on the new device with the stored information on the Backup Assistant website. If there is conflict between the new device and the website, the device data is assumed to be more current and will override the data on the website. Launch Backup Assistant. Enter the appropriate PIN then select OK. If presented, select Yes. Notate the current PIN then select OK. Backup Assistant will automatically enter the PIN and restore contacts.
