Details on one of them can be seen on this thread over at XDA-Developers, said to have been released for the unlocked European flavor of the Galaxy S II that is currently up for sale in Spain.
The new software brings various performance enhancements to the device, along with features such as Direct Call, Smart Stay and Pop-up Play, the TouchWiz Nature UX, Samsung’s S Cloud services, new lock screen, and more.
