Around a week after the PSGroove was made downloadable and free to the public, Sony has released a mandatory firmware update 3.42 for the PlayStation 3, effectively stopping the jailbreak for now.
Not that this is a surprise, but foregoing the firmware update will prevent access to the PlayStation Network. So, at the moment, if someone wants their console cracked, they’ll have to trade online functionality. Of course, as is the relationship between crackers and companies, Sony will probably be caught in an ongoing tug of war with people insistent on creating jailbreaks for the rest of the console’s lifecycle.
Yes, it’s an overall loss for Sony, but they should at least be proud that the jailbreak took four years to materialize, probably the longest amount of time it ever took a hacker to crack anything made for public use in modern times.
