iOS < 4 cannot upgrade to the latest Facebook app. The old facebook apps have this problem: When authorizing from this SDK, it will task switch to the old Facebook app which does nothing when the "Login" button is pressed on the Facebook app (it will never return to your app and won't give access... Cancel button works fine, though)

Because iOS < 4 users are forced to use old Facebook apps that don't work with this SDK, the SDK should not try to authorize by task switching to the facebook app, but should instead use the safari method, which works fine on these devices. A simple iOS >= 4 check would solve this issue.

Thanks,
Allen
