Size of Apple DRM

Hi All,
Does anyone know the exact size of the apple DRM that gets attached to our application when hosting it on App Store. I want to know how big an application I can actually make without exceeding the 10MB device download limit imposed by Apple. The 10Mb limit includes the size of the DRM + your zipped application.

It seems that the DRM size is about 1.5 Mb. Although some information elsewhere led me to believe that the Apple DRM size is 5.1 Mb. Could you comment as to whether this could be true by any chance. 1.5 Mb would be a huge relief for me. :)

That's not really DRM. It seems like Apple uses a different compression level than we do. All the non-game stuff I've looked at in games I've bought only amounts to 150k or less.

Ronny, so what you are saying is that the Apple DRM size is in addition to the size that is displayed on the App Store for an application?

What Apple DRM, anyway? It's just a couple of certificates and such. A few kilobytes each. The ZIP method they use simply uses worse compression, though.

I can confirm that all my apps end up being about 1.5MB bigger than the zip file as well.

Is there any way to figure out what will be the final size before you submit the game?

I'm wondering if that is metadata passed to iTunes, but not further. What do you get if you download the AppStore version? What size is the IPA if you uncompress it and re-zip it?
