Symbian^3 (S^3) is finally here! S^3 is the first entirely open source release following the platforms transition to an open source license on February 4th, 2010, which was the largest of its kind in history. S^3 brings with it multiple homescreens, HW Accelerated Graphics, single tap throughout the UI, pinch and zoom with multi-touch and a visual way of multi-tasking. The S^3 code is expected to be complete by the end of Q1. Check out the demo after the break.
