iOS App Launch (Default) Images

Hello,

Just tried to push to Apple and recieved the following error:

iPhone 5 Optimization Requirement - Your binary is not optimized for iPhone 5. New iPhone apps and app updates submitted targeting iOS 6 and above must support the 4-inch display on iPhone 5 and   must include a launch image with the -568h size modifier immediately following the <basename> portion of the launch image's filename.  Launch images must be PNG files and located at the top-level of your bundle, or provided within each .lproj folder if you localize your launch images. Learn more about iPhone 5 support and app launch images by reviewing the iOS Human Interface Guidelines and iOS App Programming Guide.

I am working in Flash Builder 4.6.

The Launch image included & checked in the package contents. I am using Flex 4.6.0 with AIR 3.7 with the Starling/Feathers/Flox framework.

Default-586h@2x resolution: 640x1136

Default@2x resolution: 640x960

iPad_Default resolution: 1024x768

I feel like I must be missing something. Any suggestions?

Thank you,

- Zach
