Hi
I tried out Kubuntu-Mobile [1] on my GTA04.
Considering that it’s a whole KDE4 there on this little smart phone it runs surprisingly fluent.
Nepomuk still fucks up, and also the layout is a little bit suboptimal for this small screen (2.8″!)
But after all: I’ve got KDE4 running on a smart phone!
Yeeeha! ^_^
