Good news. Waiting for a slim fix though since I have to downgrade for a friend who mostly uses his ps3 as blu-ray player, lol. I would try giving him my flash2/3 if it has a good chance to work.
and @spok: There are ways of making your retail ps3 into a debug ps3 in the making (project rebug). I'm not 100% sure but I think you can disable HDCP on debug firmware too. I guess you'll just have to wait a litte longer for it to work flawlessly
