You can add your Facebook contacts to your iPhone addressbook. This in turn will bring the contacts into Covve. Please note that it is not possible to make any changes to your Facebook contacts from within Covve or your iPhone. As such, any changes you make to these contacts in Covve will not be reflected in your iPhone or Facebook.
To do this, follow the following steps.
1) In "Settings" select "Facebook"
2) Enter your Facebook username and password and Sign-In
3) Once you've signed in select to allow Contacts to use your Facebook account
This will now add your Facebook contacts to you iPhone contact list. When you next open your Covve app you will be asked whether you want to add Facebook to the list of iPhone contact groups that your Covve account synchronizes with.
