I am getting this warning message in an iOS app using FB auth:

ERROR:This endpoint has been deprecated.To temporarily reenable it,you may disable the "august_2012" platform migration. It will be disable permanently on August 1,2012.

The issue is to disable that migration for now. But, it was already disabled, so not sure how to fix this quickly - as opposed to updating the app and pushing it back out to the store which we will do.
