Im having a really annoying problem and I cant seem to fix it. Me and my girlfriend want to play Fruit Ninja multiplayer by one of us inviting the other through GameCenter to a game. It simply will not work though. I'm usually a whiz at iOS devices so you can save the easy answers. We are both running the latest software (4.3) on our iPod Touches (a 2nd gen and a 4th gen). We are both connected to the Internet and we both have GameCenter enabled. We also have GameCenter notifications turned on in settings. We both have the game open and one of us invites the other but the other person never gets the invite. I'm completely bemused as to why this won't work. We briefly tried it with Bluetooth and that didn't work either. I'd love to hear any suggestions because it's really frustrating. Thank you!
