The firmware that will disable the OS Install function on the PlayStation 3 is now available for download. Upon signing on the PlayStation Network, you will be prompted to download the update. Yes, it is mandatory and you will have no other choice but to download it. Deal with it, it will help the PlayStation 3 have less pirates.
The firmware download shouldn’t take that long since it’s around 100MB. I don’t see that the firmware affects anything yet. We’ll inform you if it does.
