How do I change my istore preferences
I want to download apps from the AppStore but every time I press download, this warnings comes out and says: "your account does not belong to this store. Your account is not valid in the Peruvian store. You must change to the us store before you buy". So how do I change my store preferences from Peruvian to USA? In my account I put my current address from us ...but still I have this problem.
