title: Can I invite/notify somehow another iPhone user that does not have the my application to a Game Center match?
body: <p>I'm making an iOS app that has the possibility to challenge friends trough Game Center. If i invite a friend that has the application it's ok but if he doesn't have it, then the find match Game Center controller says directly that he refuse the invitation.
