On newer consoles it has metldr.2 <== 'hence the 2" which is harder to break but has been done but "mathieulh" won't say how which is up to him and I support his decision as its his work, but to me its irrelevant as my console has the older version but until someone actually comes out with a way that everyone can use then its not going to happen. Sony fixed the newer consoles so that you couldn't get back to 3.55 simply because its totally broken an they know no possible firmware update would ever fix it completely so instead made it so newer models would have more protection against hackers.
An for your second point I wish you all the luck getting one buddy :D
