Great news, everyone!
At the beginning of this year I have applied with TSPSG to Qt Ambassador Program [2]. Recently, my application was accepted and now TSPSG is featured in Qt Ambassador Showcase [3]. You can find it here: http://qt.nokia.com/qt-in-use/ambassadors/project?id=a0F20000006KW1cEAG [4].
Additionally, as Qt Ambassador, I will receive Nokia C7 [5] that will enable me to test TSPSG on a real Symbian^3 device. So all future releases of TSPSG will have a Symbian build.
