No. With Sideline Pro, there is no sync between iPhone contacts and Sideline contacts. This includes Notes and any contact detail edits that were made after your initial import of contacts/notes into Pro.
This was intentional, and the lack of automatic syncing with iOS and Sideline Contacts helps you to keep work and personal life separate.
For more information on this, please visit our article on Sideline Pro and the separation of business and personal contacts.
