Yes, but you will need your own developer accounts.
Would it be possible so that the app only works for users in a specific user group?
I'd be interested in the branded option but then recouping the cost from our members (who've already said they'd be happy to pay for mobile access).
Rather than setting up a developer account, charging in the App Storea and giving Apple 30%, if the branded app could be free in the app store but only work for users who were in a "donators" usergroup on our site we could handle the payments ourselves and simplify it all considerably.
Just an idea, don't know if that's an option or not.
