There is Necessitas Qt 4.x port for Android that is pretty solid and was contributed to Qt Project quite recently (http://blog.qt.digia.com/blog/2012/11/08/necessitas-android-port-contributed-to-the-qt-project/ http://blog.qt.digia.com/blog/2012/11/08/necessitas-android-...). I have not found good iOS port when I was looking for one. At least for BlackBerry it already is - you can write Qt apps for BB10/PlayBook OS just now.
