Nobody said it was an "easy fix". I said it may work as I had the same problem with my girlfriends fathers TV. Only supports 480p and 1080i. I played Heavenly Sword there the day I purchased it and it ran it in 1080i although the games box said it supported up to 720p.
Take a chill pill buddy.
Not sure if it is just this game, if it was an older update, I don't know. What I can tell you is that many of my games did not work this way and most got the same black screen you are having. I just seemed to have luck with HS and UT3.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
