(adsbygoogle = window.adsbygoogle || []).push({}); have a few questions and if someone could answer them it'd be much appreciated!

Currently I have a ps3 fat on 3.55 CFW. Should I upgrade to 4.4cex?

If I do upgrade to 4.4 cex, is there a working version of multiman?
And if I sty on 3.55 is there a spoofer that is working?

Thank you all for your time!
