Earlier tonight, I was able to un-YLOD a ps3 phat which I got for free. I'm curious as to what I can do with it. Its current firmware is 4.71, it is the very first model (CECHA). I know that CFW requires a firmware of 3.5, but looking around, I was given the impression that early phats/slims are downgradeable? If anyone has some info for me, it'd be much appreciated.
