I have a PS3 FAT CECHC04 60GB OFW 3.66. I though I can jailbreak it with progskeet or teensy, or in worst case use cobra ODE. But today I just come back from the shop specialized in this kind of things, they said I have a limited version of cpu, that they can do absolutely nothing, except change the hard disk for a bigger one. Is it possible ? I would like to be sure before to update my firmware. From the other side I am happy to keep my internet connection, but I will have to spend come bucks for all the ps3 games I planned to play.
