The new firmware (which, by the by, has already been decrypted) will, as every firmware before it, attempt to prevent people from running unsigned code on it. In the future, I’m sure it will also be required to run the newest games. Odds are by the time that’s an issue, there will be a custom firmware released that will give you all that nifty new functionality and still allow you to run unsigned code.Personally, I wonder if Sony’s only making token attempts at this point, though, because it seems like the hacker community is one of the better reasons to own a PSP.”]
