Well, why don't Apple keep the zip file in appstore. I have no idea about the performance issues while extracting zip file with iPhone's CPU...

PS: any Unity iPhone programmer here?

What? Since when does the appstore use the zip format for downloads? And the added drm also increases size.

zip = compressed

unzipped = not compressed

When it's compressed it's less memory but when it's not compressed it's the whole thing.

hmmm... it shouldn't be that different. The zip file size and the size that appears on the app store are around the same for me.

unless apple has changed something...

I'm not a Unity programmer. I'm only referring to regular Xcode...

Maybe Unity is different somehow... hope someone can clarify.

ipa files are zips in fact. So there shouldn't be much of a difference.

PS: You can purchase your app, and look inside the ipa to see what happened.

Maybe Apple added subliminal messaging for all the iPod Touch owners who haven't paid for 3.0 yet.

DRM, in my experience, only adds about 1.5MB to the file size. So if your zip is 5MB, your app store size is 6.5MB. I've gotten burned a couple of times, releasing games that were 10.2MB or so big. But it's fairly consistent.

.ipa files are just renamed .zip files.

Whatever Apple does to the apps makes Unity games in particular compress much worse than just zipping them the usual way. Mine's about 12MB when submitting, but it ends up 17MB in the store. However, if you decompress the .ipa file, it ends up 23MB, only 60K larger than the original.
