Sony has released a new ‘mandatory’ firmware update for the PlayStation 3. Entitled “3.42”, the update adds “additional security features” according to Sony. If gamers don’t update, they will not be able to access the PlayStation Network unless they play around with a proxy server bypass (and that will only last until Sony clamps down on it again). Homebrew/backup fans across the internet have confirmed that the patch currently stops the PSJailbreak and PSGroove exploits. So if you want to be homebrew/backup guaranteed, stick to 3.41 (for the moment).
