The PSJailbreak hack is reportedly detectable by Sony and the platform holder could be set to ban users across PSN.
The PSJailberak USB device reportedly allows you to back up and run games from the PS3′s hard drive. This means you could play games for free using the device. But Sony is aware of this and is apparently able to detect and ban any users from the PlayStation Network if they are caught using said device.
Sony has yet to issue an official statement on the recent PS3 hacking, probably since they are hard at work on a new firmware update which will combat the problem and prevent the USB device from working.
“According to [sources], the Backup manager game ID (LAUN-12345) could be logged/recorded by Sony when logged into PSN (when online). This would obviously allow Sony to see who would be using the illegal PSjb/clone and we could very well see ban waves similar to the Xbox 360. Sony does currently ban PSN/consoles that results in the 8002A227 error code.”
