Why not offer a software to block some incoming calls on the iPhone?? A shareware already exist for that purpose but is not sold in the iTunes Stores... why? Do I need to "unlock" my iPhone to be able to use a software blocking calls? It is called MCleaner. Why can't we find that app in the Store?? Here in Canada, Fido can't block calls like At&T. So if you have unwanted calls, you cannot do anything except to put a silent ringtone! I want that my iPhone stop to vibrate when there calls (telemarketing) try to reach me.
