I'm new to the PS3 scene but I managed to downgrade my console to 3.55 and have a True Blue dongle...
I'm happy that True Blue allows us to play newer games (that require > 3.55 firmware), but I'm disappointed that you can't update these games, or update several other games because a lot of newer updates are requiring newer firmware.
So... when PARADOX is releasing patched EBOOTs, why don't they also release a patched version of the game update? That way not only do we have a working EBOOT for the game, but we will also have the latest update.
(Maybe I'm too concerned about game updates, but I like everything to be on the latest version for bug fixes, extra content/changes, etc).
