I must admit, the official Jellybean leak is AWESOME! Since I have WiMax in my area, this will be my daily driver until the official version is released!
If you mean FJ10, it's not recommended since it's "buggy". But custom roms are more stable. But can get it from xda.Were did you get this from? Im stock rooted is it complicated to install.....and.... How is your phone and 3g signal compared..
