Am I missing a setting where we can assign all people in the phone book one ringtone, and all non-phone book people a different one or is there not one of those settings? We want to do this on my husband's phone, because the only calls he gets not in his phone book are work related, so he wants to have a ringer for people he knows vs work. He doesn't have many numbers saved, so if I have to go in there and assign one to everyone individually, fine, but I was hoping there was a way to avoid that, because, well, I am lazy.
