You should be able to use a 3.55 downgrader pup to downgrade from 4.66 Cfw back to 3.55,then you can select which Cfw you want to install from there.
But for specifically modding games online I would jump to ps3ita 4.50...just my opinion,good luck :-)
Thanks for that bit of info. Do you know what's a good place to get a 3.55 cfw file and a tutorial because I don't want i stuff up. Also if I do stuff up will I lose the jaikbreak?
