iCaller Location - iCaller Location (FKA i,Call Manager Ex) is a freeware application. iCallerLocation shows the area code, city, and state of the incoming caller (United States only) and pinpoints the location on the Maps. You will know where the call is coming from within the United States (will cover all cities in North America in the future). Mapping caller?s location is automatic with every incoming call. How does iCaller Location work? It?s very simple, on all incoming calls the application looks up the area code from the local database and displays city and state on the incoming call phone screen; or send city and state to Maps to pinpoint location automatically. The application uses actual and valid 443,435 NPA/NXX combinations in the North American Numbering Plan.
