Hello. I am trying to make some loading screens for iOS 6 but i cant get them to work.

So far i have tried...
- "Theme Name".Theme / Folder / "Whatever".app / Default-568h@2x~iphone.png + Default-prefs-568h@2x~iphone.png
- "Theme Name".Theme / Folder / "Whatever".app / Default.png

But no luck.
Can anyone help?

Thanks,
Chris.
