you should search more and read more too. geohot cfw was like 2 year ago or something.
you can install everything on any cfw... if you want to play games go rogero, if you want to use ps3 features and other stuff's go rex, if you want to work on homebrews or install homebrew's go 3.55 kmeaw (or rebug 3.55 )
but pal we are talking about a subject when you currently arent on cfw. so whats the point of all this??
