1. Just enjoy this video 
2. Bear in mind that this is NOT the final or official Symbian UI developed by Symbian Foundation that uses Qt. This is just a concept from developers.
3. The company developing this concept is Tieto. They also attended SEE09 to demonstrate their techonologies.
4. The concept UI is running on an existing S60 5th Edition (Symbian ^1) smartphone.
5. Lets hope more goodies will be made available for Symbian
