OK I have been reading alot and this firmware interests me a lot as i'm currently on 3.55 Kmeaw from a couple of years ago my PS3 has never been on a higher firmware (thats OFW or CFW) i have a few doubts though.
1. i only use cfw to play games.. so is it worth me upgrading to this?
2. whats this QA i keep hearing about?
3. also what is it about backing my NAND up?
thanks for any help
