A word from rogero we might get a 4.55 cfw: Hello, I hate to feel like i'm ignoring anybody, especially my fans and user base, but real life was so demanding lately and I didn't have any time to keep up with the ps3 work, actually I dedicated a lot more time to spend with my 2 kids and stepped away from my usual "geeky" attitude I may work on 4.55CFW as my free time allows (no promises of anything or ETA here, i will just try to check about the changes in version 4.55 and build a proper CFW)
