Yes we have another Firmware update for the PS3. Many believe this is nothing more than a kill switch for the new PS Jailbreak, PS Groove, PSFreedom and any other exploits that won’t work after the latest patch.
The firmware was released this morning and is mandatory, so if you want to online or purchase from the PS Store than this is the only way to go.
Sony is attempting to stay ahead of the hacking community now that the once unhackable system has seen its safe guards broken.
