Over the last few weeks there has been a lot of discussion regarding the jailbreaking of the PlayStation 3. Late August saw the availability of PS Jailbreak, a USB hacking tool from an Asian company. However, it seems Sony is aiming to nip things in the bud with the next firmware update.
The BBC reports that, though the release of the latest update for the PS3, 3.42, doesn't add any functionality, it does block both the PSJailbreak and PSGroove applications. This is a mandatory update, which means if you want to continue PlayStation Network or the PlayStation Store you have to update.
Sony recently won an injunction against two Australian retailers who were selling the PS Jailbreak dongle. The injunction was a temporary one, lasting until August 31. Sony had until that date to make a case for a permanent ban on the PS Jailbreak USBs. According to the BBC, Sony also has also taken steps to stop the sale of the dongle in the U.S. and the Netherlands.
