You could get access to the full friends‘ user profile data in Graph API earlier than v2.0. If you had 500 friends, and granted friends_* OAuth permissions to an app, the app had access to 501 user profiles.

I was possible to use the v1.0 API until Q2/2015 if I remember correctly (only if you had a v1.0 app though)
