WWDC 2023 is coming on June 5 - Here is everything you need to know about the event!
Don't bother doing it through the Facebook app...I've had plenty of friends where not everyone synced up, among other problems.
Download the "SmartSync" app. All I did was change a few settings so it only syncs Pictures and Birthdays and it'll match up ALL of your contacts, whether your Contact name matches their Faceboook name or not.
Awesome app.
