Even though AOKP ROM – famous for its customization options and performance – based on Jelly Bean hasn’t been officially announced, each day a new device seems to be getting an unofficial port of AOKP. XDA Senior Member Rushabh25 has released an unofficial port of AOKP ROM for the Galaxy S2 which brings along Jelly Bean Android 4.1 with all its features such as a smoother interface, improved notifications menu that lets you perform actions right from the notifications, advanced voice recognition, offline voice typing, a smarter keyboard, and more.

NOTE: Keep in mind that since this ROM is a work in progress, there may be certain bugs and issues and some thing might not work properly. Also, AOKP based on Jelly Bean is in its early development stages, so not many customization features of AOKP are currently present in the ROM.
