A new firmware for the Xbox 360 has been released that bypasses the new "fix" that Microsoft introduced that would prevent users from playing online with a modified console.
This new "stealth" firmware prevents the Xbox Live service from detecting that any modification has been done to the DVD drives firmware.
Currently, there's very little information about this new firmware, but the makers claim that it will hide your modified drive from all current and even some future detection techniques on Xbox Live.
