Many people in this thread said that using the method like in browser search for an app only exist in another country, click the link to app store and the prompt message will ask you to switch stores to another country.
This method I don't know why not working for me. I can get the prompt message and the store really changed to another country. However, when try to down an app, it still prompt another message saying your account still in original country, and ask you to switch back to your original country app store.
For me, using a link searching another country app and link to it, answer to switch app store is not working..... I can change to that another country app store but still cannot download an app there......
