A jailbreak for Sony's Next Gen console PS4 has been released today by a Team known as Redox. The PS4 released on the 29th November in the UK and just one day later Redox claim to have a working Jailbreak.
The jailbreak bypasses a system security check using a memory exploit which occurs with USB devices that allows the execution of unsigned code.
You do not need to open up the PS4 to be able to use this Jailbreak all you will need is Team Redox program
Team Redox Have this to say:
Xpgamesaves does not condone piracy or online modding.
The legitimacy of this has yet to be confirmed, but we will keep you updated as soon as we have more news.
