icon sizes for iOS app?

[mobo]

I found these steps in the submittino guide on Adobe web site:
***************
Application icons should be supplied as PNG files in the following sizes to support the currently available iOS devices: 57 × 57 pixels, 72 × 72 pixels, and 114 × 114 pixels. One additional size, 29 × 29 pixels, is used for Spotlight search results on the device, and is optional. These icons can all be specified on the Icons tab of the AIR for iOS Settings dialog box in Flash Professional or in the AIR application descriptor file in Flash Builder.

App Store icons are 512 × 512 pixels. For development builds, this icon is included in the application package and is referenced in the publish settings or application descriptor file. However, you should not include it as part of the application for the final release. The App Store icon for the final release is uploaded separately using the iTunes Connect website.

Launch images are included in the root directory of the application package but are not referenced in the publish settings or application descriptor. iOS loads the correct image based on the filename. The name will be a variation of Default.png. iOS chooses the variant depending on the device and how the application is invoked. The most effective way to take advantage of this iOS feature is to use it as a way to make a perceived performance boost to your app. Use the launch image to make your app appear to load faster. In most cases, it should be the same as the first screen of your application or a splash screen. Simply taking a screenshot of your app at startup often will be sufficient as your launch image. Another way is to export the background of your app from Flash Professional and save that as Default.png.

However, the options in the app properties are somewhat different. Two icon sizes 114 and 512 (which is not needed apparently?). What about the other sizes (57 and 72)?

These are all for different parts of the app. The big ones are for iPad and iPhone app store, and the other ones are things like notifications and icons in the settings menu.

I think I was not clear in my question. I don't see the smaller two icons submission dialogs in the iOS app options panel. Are they generated automatically behind the scene from the bigger ones?
Also, the option for submitting the bigger one (512) is present even in the FINAL iOS app options panel....but in the article above it says don't submit it.
I am just wondering if the final compiled iOS app will comply with the Apple's guidelines.

Thanks,
