A new firmware update is now available for the PlayStation 3. Firmware version v3.42 doesn’t add anything new to the software, but simply includes security fixes for the console. The new update disables the use of the recent USB dongle hack, whether it’s the Groove, the Jailbreak, or the PS Freedom.
The PlayStation Website simply states:
A security patch has been added to address security vulnerabilities in the system software.
so… what happens now with the jailbreak? :]
