Newest tweet from KaKaRoToKS says that his current WIP jailbreak works with PS3 FW 4.0. There is no current release date, or time frame for the JB release.
KaKaRoTo has just recently updated his blog, with this message:
I tested the jailbreak on the latest firmware 4.0 since it was released and I can confirm that it still works. Mathieulh also confirmed that the NPDRM algo that he has still allows applications to run on 4.0, although he still doesn’t want to share that with us/me at the moment.
Mathieulh is still thinking about whether or not to share it, so I’m hopeful he’ll help us move forward with the release.
He has however received so many hate messages and so many flaming that he is completely disgusted with the scene and the way it treated him. He is so disgusted that he does not want to share or help anymore. He thinks that all those haters do not deserve to be given something that they are so ungrateful for, and I perfectly understand his position. Receiving all that hate towards me a while back also made me depressed to the point I stopped looking at the PS3 entirely.
Next time you want to insult a dev, thinking it’s “fun” or that he deserved it, think about it some more, you are poisoning the scene without even realizing it. We are all doing this for fun, the only reward we get is people’s gratitude, and all you do is hate and disrespect us, so why continue to do what we do?
For those who hate and insult : Mathieulh may not be acting the way you want him to, you may think he’s a jerk or hate him for teasing without releasing, but the simple fact remains that he has done more to the scene that you did, so you should just shut up and show him respect. When you have your little ‘hate fun’, you are actually contributing to the scene, but in the wrong way, you are killing it by killing the developer’s motivation.
For now, Mathieulh doesn’t want to share his work with me, and I’m not mad or disappointed at all at him, I am mad and disgusted at those who made him make that decision. So please, if you are just as mad as I am, do NOT make this an opportunity to hate even more on Mathieulh for not sharing, make this an opportunity to show gratitude where it’s due and educate those who are ungrateful on what their role is/was in this scene.
