Here is what you get when you try to connect to the iTunes Store in Brazil:
I discovered this while trying momentarily to authorize one of my friend’s computers to read a movie I had purchased on my computer.
Well, I researched the problem and found this petition. It looks like iTunes Store is not available in Brazil, my guess is for fears of piracy, but I’m not sure. The problem is that the use case above is perfectly legit, yet, impossible to support in Brazil.
