Hmmm, the problem with qtmoko is that it works so great that
you do not have to reinstall it very often. So I forgot
which version I have installed.
Is there an info screen somewhere where I can see the installed version
number ?
System info says I have Qt Extended version 4.4.3 built on 4
fev 2010. Is it v19 ? :-)
