The ebook works any where in the world. The only problem is that you cant access the sony store from the ebook. Bought mine from us ebay
When you buy the ebook connect to your computer and it will auto setup the sony reader program. You can download from any store I use diesel,ebook.com,booksonboard,ebookmall, and have sent some money to an American via paypal to get a sony gift cert to download from sony.
When i register for these sites I use an American address as a lot of them wont let you download all the books.
My other reader uses mobi pocket - jteck 100 from HongKong.
