There are some apps which are available in the US App Store but not in the UK one. For example, I'm trying to get Mobile Magic Disney as I'm going to Florida in August. I have found in several places on the web a method to use a different email address from usual, logout from UK App Store and in to the US one and create a new Apple I.D. while buying a free app. This doesn't work for me as it should apparently show an option to not set up a Credit Card and use a "None" option. This isn't showing.
Is this a loophole which has been closed by Apple? Why does it matter which countries can see which apps? And is there a way around this please? Thanks.
