i've heard about the ability to create a new user on your XMB and say your living in XXX location. I used it myself to say i'm out of hong kong and then download a namco beta game for HOME. Maybe you can do this aswell, just start a new user in you PS3 and say your in the states (or anywhere they have the DLC) and then download it, once it's done, delete the new user account and nothing changes. I have done this myself and it works.
Well they finally managed to release the DLC in other European stores than just UK. I bought the Jedi Temple, it's very short and as for costumes and skins, there is nothing in the world that would justify their ridiculous price. They ought to reconsider the pricing.
