Can anyone suggest an article or perhaps an example of how to create an “infinite drill-down” with UINavigationController like you see in the Facebook, IMDB and BrightKite apps?

Never having done this… I would approach this by keeping a stack with a light-weight object containing the contents of the previous view (perhaps just a URL?). Rather than just push on a new UIViewController to the UINavigationController, you would pop your current one, without animation, then push on the new view. However, I don’t think this would properly handle the nice animation.
Another way that comes to mind would be to manipulation the viewControllers array of UINavigationController. After pushing on a new view, just remove the previous view from the array. That way the UINavigationController stack would only ever be 1 or two elements deep. Handling the back button would create the proper view, insert it into the viewControllers array, then pop off the current one. Your state would be managed by the lightweight object stack, not heavyweight view controllers.
