What is an alternative solution to remove display = wap Conversations in the Facebook Authentication Settings dialog box?

I am currently authenticating my facebook application by passing the display = wap parameter along with my authentication url. But it displays an error message: " An error occurred with the" Application "on the mobile device. Try again later. API error code: 11 API Error description: this method is out of date Error message: Display = wap dialogs are out of date. You can temporarily enable them by disabling the july_2012 migration. They will stop working permanently on July 1, 2012. "When I turned off the july_2012 migration, authentication works correctly. So, how can I process my applications after July, and what is the correct and permanent solution to this problem.
