(adsbygoogle = window.adsbygoogle || []).push({}); is it now possible to jailbreak 4.46 like having a 3.55 before?

been gone from modding scene for a while but ive seen so many new modding
eg CEX DEX and such

but ive also seen a 4.46 cfw!?!!?!? does this work like having a second ps3 that is on 3.55 like i have?

4.46 CFW basically just used for to go online or something like that, most people will just use a spoofer, but you can only use the 4.46 CFW if you're on 3.55 OFW
