I've noticed that my contacts on my iphone 6 have a couple of people who somehow snuck in there from Facebook. It's quite possible I don't have their phone numbers, and they are not my friends in real life. They also don't show up in my icloud settings, nor do I see them on my old iphone 4. And I can't delete them! There is no 'delete contact' option in the contact edit section like there is with everyone else. What gives?? So . 1) How can I get these people off my phone? And do so while still keeping them as Facebook friends? 2) Prevent this from happening again?
