I was wondering what the various advantages between having multiple iTunes store accounts on different stores vs. just changing countries in your account were, besides convenience. 1) Is there any advantage to having apps/songs bought from different stores but under the same account name? 2) Are there limitations to changing countries on your account? (like limited number of changes, or a wait period between changes). Anything stopping me from just continually switching my countries in my iTunes store account? 3) What happens to Apps bought from different stores when you check for updates? Does it only check for the store you are currently signed into? Does it pop up saying "This is unavailable for your store" or "you need to be signed in" for apps purchased in a different store? Is it the same for one account and multiple accounts?
