iPhone CoreLocation: Give user the option to re-enable location usage for an app

Question

If a user declines permission for an app to use the user's location data, is there a way for the user to re-enable it later? Or for me to programatically give the user the option from within the app?

I commented on that here: http://stackoverflow.com/questions/2287425/what-are-the-rules-behind-x-would-like-to-use-your-current-location-on-the-ipho/2291661#2291661

You have to do this manually via the settings screen (and it's for all apps).
