Thanks. I don't keep a blog anymore or I'd do it. They have also recently denied doing this: http://www.businessinsider.com/is-facebooks-app-spying-on-me... so if anyone can show evidence otherwise, it would likely be A Big Deal.

EDIT: Sounds like they might pin certs on newer versions of the iOS app. https://github.com/Naituw/HackingFacebook might be useful to get around that. I haven't tried it.
