It was just a matter of time before coders start developing custom-firmwares for Sony PS3 console after public root-key leakage by GeoHot, the news is, that milestone has just been reached with first-ever custom-firmware being made available to public by developer who goes by name - Kakaroto.

As expected GeoHot has finally pwned Sony PS3 posting METLDR root key publicly. The "root-key" or “private key” is used by the console to block unauthorized access to system-critical portions of the internal firmware effectively preventing piracy and hacking.
