"Destructoid is reporting that the 3.42 firmware has been released for the PlayStation 3, and it has fixed the USB vulnerability that allows the PSJailbreak exploit to work."
Sony's brief announcement of the update refers only to "additional security features," though the EU blog post acknowledges that a vulnerability was addressed. PS3-Hacks.com confirms that the patch is effective against the various jailbreak tools, and they point out a different tool for bypassing the update. Sony told the BBC, "... as we always have, we will continue to take necessary actions to both hardware and software to protect the intellectual content provided on the PlayStation 3."
