title: Is it possible for a universal app to have an in-app purchase that works on iPad only?
body: <p>Just what it says on the tin. I'm thinking about releasing a universal (iPhone and iPad) app, and I'm also considering having an in-app purchase that will add functionality, but I think that the functionality is only applicable to the iPad version of the app. Is it within Apple's guidelines to offer an in-app purchase that only works on certain devices?</p>
