[ios] Max size of an iOS application

50 Meg is the max for Cell data download.

But you might be able to keep it under that in the app store and then have the app download other content after the user install and runs the app, so the app can be bigger. But not sure what the apple rules are for this.

I know that all in-app purchases need to be approved, but not sure if this kind of content needs to be approved.
