Even if the store were not supported in your country, you could still get someone to get you an itunes giftcard from a supported country. You would have to set up an account in that country though.
I set up 2 accounts on my iPad because I wanted access to the US store. There's a way of transferring money (e.g. from an itunes card) from one to another account, but unfortunately as my 1st account is in europe and the 2nd in the US, I cannot transfer my money between accounts due to currency. So I will have to get a friend to get me an US itunes card from walmart or so to finally get the Weber grill book-thingy-app.
