Uhh what? O.o 4.30 is far from broken cfw. Only thing it can't do is swap back and forth between cex and dex. Thats not rebugs fault, Sony blocked dex in 4.21+ fw. Rebug was unable to implement that, thats only difference between rex421 and rebug430. I've used all there cfw, and proud supporter of that team. None of there cfw has ever brought the word "broken" into my head. If anything, near perfection is how I see all there cfw, with nobody ever bricking going to there cfw.
