Mathieulh could jailbreak PS3 3.56 FW+

A well known Hacker called "Mathieulh" found a bug in Sony's FW 3.56 which could allow us to exploit metldr and the bootloader, and of top of that with this exploit it's possible to jailbreak every OFW starting from 3.56. But Mathieulh doesn't want to get in trouble with Sony like GeoHot or Graf_Chokolo so he will not release it yet or maybe never. :(
