Sort of off topic, but relevant.. my fear about iOS call blocking apps might be coming true. Now that there's TrueCaller, Mr Number, Hiya, etc, there are islands of data and I doubt that they're sharing with each other. This is just letting more and more stuff slip by. i'm almost at the point where I wish that Apple had their own huge gargantuan database of reported spam numbers. Or that they would have licensed Oomas or nomorobo (even though they're a paid service) or something.
