Of Course! Theres a special new 4.25 CFW out, just for us!! It has all the added security, brick ricks, compatibility issues, and gets rid of that pesky downgrading you used to do, and takes away all those worthless 3.55 CFW features you don't need: full access to your system, MultiMan, Showtime, etc. It's wonderful! All those pesky extra features taken away. Sony even did the custom firmware for us: hxxp://us.playstation.com/support/systemupdates/ps3/DONTFOLLOWTHISLINKDAMNLINK/index.htm
If your system doesn't happen to brick on the upgrade, you'll be on wonderful 4.25 "CFW". Good Luck!
(....I hope people realize that was a joke. I know your joking too, themuse!)
