iPhone Full screen camera uiimagepickercontroller preview

Question

In iOS3 to get a full screen preview a scale of 1.12412 was enough.

CGFloat cameraTransformX = 1.12412; CGFloat cameraTransformY = 1.12412;

picker.cameraViewTransform = CGAffineTransformScale(picker.cameraViewTransform, cameraTransformX, cameraTransformY);

} Scaling x and y to avoid distortion.

In iOS4 using this scaling leaves a black bar at the bottom of the screen???? http://educoelho.com/files/configurePicker_SecondAttempt.png

Also the captured photo is not centered to what you see bacause the preview is shifted

Anyone familiar with this issue? What is the iOS4 method for a iOS3.x full screen preview?
