If the author of the app provided a link to a full source code download in the app itself and on the appstore page, wouldn't that make the whole thing compliant, at least in spirit, with the GPL? Everybody would be able to download the source, build/modify it themselves and run it in the emulator and if they have a developer certificate install it on their phone.
