Before I get carried away with the iOS 7 and iPhone 5S bandwagon, there's a problem that I might have and I don't see the answer anywhere. In iOS 7, is there a way to restrict incoming calls to the Contact List (Address Book)? I have always had to jailbreak my iPhones to get this capability. Although I see many references to Call Blocking of individual numbers, I really want incoming calls restricted to the Contact List most of my work day. Please let me know if this is attainable with iOS 7 before I upgrade to something that is going to complicate life instead of simplifying it! Thanks very much for any help you can provide.
