No, your contacts will not sync across your two address books. With Sideline Pro, we purposely separate your work and personal contacts so that you can better manage communications and keep organized.
For example, if you create a new contact in Sideline Pro, that contact will only show in Sideline, not in your device's address book. The same rules apply when creating a contact in your device's address book; the contact will not sync to Sideline.
However, if you wish to import your device's contacts into Sideline Pro, you can do so at any time via your Pro address book. Visit 'How to import, create, edit and delete Contacts' for instructions.
