I notice someting on the new gamecenter on 4.1 vs on 4.0 GM. I can't use my default account for game center on 4.1 compare to what I could on 4.0 GM... I wonder why its not letting me use my default account for the 4.1 I had to make a new apple id account for the game center on 4.1 Whats the deal? When I made a Game Center Account on 4.0 GM with My Default Apple Account? Anyone having this problem? Thanks guys.
