how do you change back to the south african store from the american store on your settings??

Settings > iTunes & App Stores > Apple ID: > View Apple ID > Country/Region...change here.

Why does this have to be so complicated? Changing from your original store to another store (in order to view a product that is not in your original store) is a simple Yes/No question, but switching back to your original store is like filling out a tax form....?!

Actually, I have found that once you visit the other Country Store, you can just turn your iPhone off and back on and it reverts back to the store in the Country you are in.
