I spent a lot of time being frustrated by the documentation Facebook offers about upgrading from v1.0 to v2.0 if the Graph API and Login. However, I finally came out the other side, and I've written up my findings so that others may struggle less than I did. In two parts: The important differences between v1.0 and v2.0 (http://code-worrier.com/blog/changes-in-facebook-graph-api-2-dot-0/) How to build common features using v2.0 (http://code-worrier.com/blog/find-friends-with-facebook-graph-api-2-dot-0/) I hope these are helpful, and I'd love your feedback.
