I finally managed to get it working on my T-mobile phone.
Turned out to be that the path to the TFloCubeCtrl application is hardcoded to /program files/tFloCube/ but I had to change it to /programmabestanden/tFloCube/ (as I have a phone with a dutch T-mobile ROM).
It works like a charm now, now only to figure out how to mod the icons on the application launch screen, but I saw a readme with a bunch of information how to make your own cubes, so that should be fine
