Default load screens on iOS
===

Im making a universal app for iPhone and iPad, both retina and non retina displays.

I've looked around the web for the answer and have found conflicting answers, im not sure why some people say the default image for ipad has to be 2008 (h) rather than 2048.

Anyway, I want to know what Default.pngs I need to include with my app for the load screen. And whether each one is essential or not? Also what name each one should be called?

Thanks
