Galaxy Ace jelly bean 

nims11 of XDA has taken a good effort at combining Paranoid Android , AOKP and CyanogenMod 10 ROMS for Galaxy Ace S5830 , making it a single PAC ROM containing Jelly bean 4.1 . This PAC ROM for Galaxy Ace will have all the features of the three ROMs mentioned so one can have an almost complete Jelly bean 4.1 OS running on their handset. Galaxy Ace is almost fully functional with the PAC Jelly bean ROM, the camera & camcoder, bluetooth & HQ videos  is now working.
Things that are not functioning are :-
- USB tethering
- Wifi tethering
- Google now

So almost everything else is working and running smooth.
