76w ago - Following up on the
previous article and
update for the 3.73 JailBreak, today Sony PlayStation 3 Hacker
KaKaRoToKS has confirmed it is safe to update to
PS3 Firmware 4.00 for those planning to use the
exploit when it is released.
Below are some recent Tweets from him, as follows:
FYI, tested yesterday and the jailbreak still works on 4.0

so it's safe to upgrade (for those on 3.73)
Just got my progskeet today. Thanks
uf6667 for sending it!

It's so small!
Not much new to go on at the moment, but keep in mind the upcoming PlayStation 3 exploit will not enable PS3 backup managers such as multiMAN or Rogero as it does not include support for modifying Peek and Poke for lv1 and lv2 as outlined in the
FAQ that was previously posted.
Also, as neat as ECDSA is to me, I feel like this is something easy for a math expert to come up with. Are there really that many systems that rely on the same model? I guess if it ain't broke...
