Hi
Just FYI I think that the utility used while copying resources on the iPhone platform is "pngcrush".
It's located in
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/pngcrush
It tries to remove unnecessarry chunks and recompresses the image data.
I would not use it unless you absolutely need to preserve space.
Some programs cannot handle these stripped-down images.
Regards
Patrick

When I try to open the PNGs in the app bundle, Preview just shows empty windows. Interestingly, Default.png does display in Preview, so perhaps it's not compressed so it will load faster on app startup?
