Here are good new for all of us with slightly older VGA devices like HTC Diamond/Touch Pro. And it is that
TouchFlo3D 2.5 has been ported to VGA phones. These days the WVGA seems to be the new standard, but the "old school" VGA Touch Diamonds and Pros are still very useful.
The new interface is still in the early phase, with some features not working and some graphics not quite fitting in the smaller screens. I think this will ne stop you from trying it so head on to
Mobility Digest to download and install it.
