In recently,there have many ps3 v3.55 CFW came out, yet which one we should use and what's the difference between them ? Following,i will make a comparison of these CFW and hope can help you get little more know of them.Till now,there have three famous CFW for v3.55,such as Geohot's CFW, Wutangrza's CFW,and Kmeaw Prepatched CFW.
The brief comparison of this three CFW :
Geohot's CFW is the first one released customer firmware and allows you to install special signed PKG's and you have to use pkg's signed with geohots tools.
Wutangrza's CFW is basically what flukes1 released it just has peek/poke enabled but you can't install PKG's and like Geohot's CFW, you have to use pkg's signed with geohots tools.
