Thanks. I don't own that device. However, I can see at some place that Nokia released Qt for Maemo 5 (the one that runs on the N900 if I am correct). Not as the main UI toolkit (which only changed with Harmattan), but it was available and fully supported by Nokia (not a community port), according to those. As an example: https://en.wikipedia.org/wiki/Maemo#Naming "Maemo 5 : 25 October 2010 : PR1.3, Qt 4.7.0, full OVI-Suite support, updated kernel with kexec patches for MeeGo, bug fixes." Is that right ?
