Today my GT-I9100G repos went under the big CyanogenMod umbrella and nightly builds will hit the download servers soon.
Update Guide: http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S_II_G:_Full_Update_Guide
The builds are already pretty stable and there shouldn’t be much problems while using it as daily driver.
All features except FM-Radio, Wifi-Direct and maybe TV-Out are working.
I’ve also added a touchkey backlight notification feature (Notification LED) and some other funny gadgets.
Flashing CM9 onto the GT-I9100G is like buying a new device. It’s damn smooth and a whole new world if you’re coming from a TouchWiz rom.
If you cannot wait any longer, there are experimental builds done by me around on xda.
Hope you’ll enjoy.
