No, it has more to do with this note published by Adobe. On page 3 under "iOS SDK Upgrade", you will read that to publish an App for iOS using AIR 28, you now need access to a Mac with Xcode installed to create an Assets.car file that you can then use to package with your swf. This is a major pain for me as I do not own a Mac. Ugh.
