mWindow.rootViewController doesn't work on the iPad 3.2

[megatema]

If you try to start app on iOS less then 4.0 you get following error:

Mon Jan 23 11:00:24 UIKitApplication:com.g5e.scity.hd[0x25e4][6067] <Notice>: GLESRenderSystem::_createRenderWindow "...", 768x1024 fullscreen miscParams: FSAA=None contentScalingFactor=1.0 displayFrequency=0 Hz orientation=Landscape Left

Mon Jan 23 11:00:24 [6067] <Error>: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIWindow setRootViewController:]: unrecognized selector sent to instance 0xf2a080'

This is because mWindow.rootViewController do not exist on iOS firmware less than 4.0.

I found solution how to fix it, but did check it yet.

Also of note: iOS 4.0 is the minimum for Ogre 1.8.
