This is not hard. I assume that you are using a server which will communicate between the two devices. In this case when the person A moves you can update his location coordinates to your server. You can get his/her location coordinates using the

- (void)locationManager:(CLLocationManager *)manager 
    didUpdateToLocation:(CLLocation *)newLocation 
           fromLocation:(CLLocation *)oldLocation  

delegate method. At the same time you can get person A's location coordinates from the server and keep updating your mapview. The pin will move. Just set the pin drop animation to NO.
