Tagging creates a link between your post and a tagged person's Facebook Timeline. This tagging option is available on the iPhone's Facebook app whenever you post a status update or photo. Previously posted photos can also be edited to tag people. Regardless of your privacy settings on a photo, a tagged person is always able to view the photo. A tagged person may also receive a notification of the tag, depending on his notification settings.
