I want to add Game Center in my game. It has requirements 3.2 now, but Game Center needs 4.1. How to upgrade last version of my game? I can't just upload new version of my game with Game Center because of differences in requirements. I can't resolve this problem, but I know that Doodle did this somehow.
It can be done, what you have to do is to weak link to Game Center. Take a look at: Game Kit Programming Guide Section: Optionally Supporting Game Center In Your Game
