It’s about that time for the PS4 to get a little maintenance again and you can get your hands on it early. Sony has opened sign ups yesterday to beta test the new system software coming to the PS4. You have to be 18+ and can sign up now through early February , which is when the beta starts.
If you get chosen to beta test you’ll receive an e-mail with instructions on how to download and install it on your system. Happy testing!
