Samsung Galaxy S II got rooted within hours of it’s release. Most of the folks opting to root their devices weren’t really comfortable doing it with CF Root kernel, as their was danger of device bricking etc. One click rooting solutions like GingerBreak weren’t applicable as S II mostly shipped with patched Android 2.3.3 Gingerbread on board. But when it is Android, there surely is a way and now you can easily root your Samsung Galaxy S II [S 2] with a single click using S2Root Application. The credit for developing this easiest rooting program for Galaxy S II goes to lyriquidperfection at XDA forums. The application comes integrated with Unroot option as well.
Here is what the developer has to say about this release:
