FIX: IOS Regression: banner ad size not changed on orientationChange and IOS6 layout broken

On orientationChange, make sure banner ad size is also changed.
StatusBar support should not impact IOS6 layout.

Testing:
   IOS7 - iPhone 5, iPad 3 (Mobile App and Mobile Browser)
   IOS6 - iPhone 3GS (Mobile App and Mobile Browser)
