Not yet, as this one seems slick enough for me so far.
Now that I have used Jaf for the first time (I was very worried in case I did something wrong), I might try it one day.
This firmware includes rompatcher so it does make life easier.

Cooked roms
cooked rom is the language from WM world,in symbian, i think we call it "DIY firmware".
I am using one DIY firmware v22 for my N97, it's faster than official firmware.
and have not found any other problem, the best thing about the DIY firmware is that it cooked crack tool in it, this way you say goodbye to Certificate and signing thing, just install softwares directly.
