ok, here is a thing. I'm very much interested in downloading/purchasing DLC maps, but my Uncharted 2 game is from region 3. I have the old US account for long. If I buy the DLC from region 3 (PSN Store), log out afterward, and log in again in my old account in the US, would I still be able to play it ?!
EDIT: Never mind, I just found out that DLC is still region locked by different profile user. *sigh*
