Where did SBSetAirplaneModeEnabled function go in iOS 3.0+

Does anyone know how to enable/d开发者_JAVA百科isable airplane mode in iPhone SDKs after 2.x?

I need to create an app that legitimately disables the radio for the duration of its execution. Is Apple likely to permit this soon.

I followed http://blogs.oreilly.com/iphone/2009/01/bring-airplane-mode-control-ba.html

but setAPMode pointer is null.

Steve

AppSupport.framework's RadiosPreferences class has an airplaneMode property that works (as of iOS 4.3)
