UPDATE: As of May 2015, Facebook has turned off their APIs to the majority of their developer partners worldwide, including Scrubly. Unfortunately, Scrubly will no longer be able to provide updates to your address book from Facebook.
Update Your Contacts with Your Friend's Latest Facebook Information
With Scrubly, you can now import all of the rich contact information that exists in
Facebook to enhance and update your contact list.
Scrubly only pulls in information for contacts that already exist in your address
book, it does not import all of your Facebook friends.
Even if you only have an email address as a contact, Scrubly will sync up and
complete your contacts from Facebook data.
Control Exactly Which Contact Information You Want to Update
You have complete control over the information you want to sync and import from
Facebook. Select the fields you would like to sync. You can turn on or off Overwrite
so that any existing information in your address book will be either overwritten or
Scrubly does not import all of your social network contacts. It only updates the
existing contacts you already have inside your address book.
