I've published a few apps that run the same platform on different countries with different branding (name, logo, theme, etc.)

I had to restrict each of them to their own country (i.e. preventing German users from reaching the French app), otherwise during the app-store submission reviews, the reviewer would reject us because according to them the app being reviewed is a ripoff of the other apps of the same account.

It's like:

    Your app "Gmail UK" is a ripoff of another app of the store: "Gmail US".

Fun times.
