How to change my iphone app store back to UK version?

I downloaded an app that could only be downloaded from the US store and so it automatically changed but now I can't figure out how to get it back to UK store. Help please? (:

Go to your settings on your phone and go to "itunes and app stores". At the top you should see "Apple ID: (your apple ID)". Tap it. A pop up should, well… Pop up with: "show apple ID" at the top. If you tap that, you need to type in your password.

When you did all of this correctly, you'll see a screen with some of your personal data. With also your country. Just change it to UK and you should be fine.
