I've tried going into settings > Facebook > update all contacts, but it just matches the contacts with my FB friends profile pics, but doesn't give the option to manage them. What if I have two contacts with the same first and last name, and they are matched incorrectly? Is there a way to manually fix that? What if a friend uses a different name on FB (e.g. nickname) than the name I have on my contacts? If manual fixes can't be made, does anyone know of a good app that accomplishes this?
