Finally, after much waiting by owners of the original Galaxy S2 I9100, the official CyanogenMod 10 (CM10) ROM based on Android 4.1 Jelly Bean has been released for the device by XDA Elite Recognized Developer codeworkx, which many thought was never gonna come. CM10 combines Jelly Bean’s features – a smoother interface, smarter keyboard, advanced voice recognition, improved and actionable notifications menu, etc – with CyanogenMod’s proven performance and customization options.

NOTE: This CM10 release is an extremely early preview releases, so it may contain a lot of bugs and a few things might not work correctly. Also, do not expect to see many customization options of CyanogenMod to be present in the ROM right now as CM10 is in its early stages.

Galaxy S2 I9100G owners can try out CM10 → here, while Galaxy S3 owners can try out CM10 → here.
