Samsung Galaxy S2 is hogging the limelight well after completing more than a year's stint in the Android market. The S3's predecessor still commands respect from Android fans, thanks to its regular custom ROM updates from developers.

The Galaxy S2 has already received the Jelly Bean goodness through several flavours of CyanogenMod 10 (CM10) ROM. With due credit to XDA senior member ICS_XD, the latest ROM, Jelly King CM10 v1.4, hits the i9100G variant of Galaxy S2. The Jelly King ROM blends the goodness of CM10 ROM with fluid Android user experience, thanks to Jelly Bean's butter smooth interface and slick performance. The new CM10 ROM, however, offers a different set of icons and themes.

The prominent features of the ROM are listed below:
