The Samsung Galaxy S2 has yet to receive the Android 4.1 (Jelly Bean) update but some developers have been successful in running the Jelly Bean-based AOKP and CynogenMod 10 (CM10) ROMs. Android Soul now reports that developers from the XDA forum now have a new custom ROM, which combines the two and makes it compatible with the S2.

The Vanilla RootBox Jelly Bean 4.1.1 ROM, according to claims made by the developers, is built from RootBox sources and is a pure AOKP/CM build without addition. Basically, what they're saying is that when installing users will have the option of choosing extra apps. However, the ROM is still in development stages, so be warned there will probably be bugs.
