We don't even know they always did this with permission, because in the past they didn't actually need permission for it, which could be why Facebook is trying to make such a big deal out saying that collecting call history and text is "normal" when they collect your contacts.

It was required in 8.0 to tell the users that they're collecting this data. So the question is, did they collect it before 8.0 w/o permission?
