"The PS3 users are forced to download the PS3 3.42 Update as it has been mentioned as a mandatory one. If the users fail to update their PS3, they would not be able to login to their PSN account and even purchase from the PlayStation store."
that's the key(for right now, unless you use the bypass method which im sure you can google or youtube), it's like sense and non-sense CM 6, if you want 4g, you cant use cm6. Pick what you want. Off topic but im an Ava man till the end lol.
The 3.42 as of now removes jailbreak,groove and all usb methods of this hack.
