“So, apparently, Sony released the latest firmware update for the PS3. It seems as though the PS3 can now block the PS3 Jailbreak at its current state. I’ll give it a week before a modified version of the hack works with the updated firmware.” -Crait

I don’t know if it will be that quick, but Sony definitely put some effort forth to get a firmware update out to block this thing. I guess the PS3 will have the same circle of cfw and ofw updates in its future! According to the BCC the update blocks both PSJailbreak and PSGroove applications.
