has anyone played around with the 3.0 update's GameKit APIs at all? I heard it's really simple to make a game such as bejeweled now.
From what I've read it is a networking API.. they make it much easier to have local(?) networked games. I haven't heard that it involves anything outside of networking..
GameKit doesn't change anything how games like Bejeweled are developed. GameKit makes it easy to add multiplayer functionality and VoiceChat (Bluetooth or Wifi) to games and other apps.
I'm guessing then that this is something different? http://www.iphonedevsdk.com/forum/iphone-sdk-game-development/14882-has-anyone-tried-new-3-0-game-features.html
