There is an update for Skype on Diablo you can see the packages here http://catalogue.tableteer.nokia.com.../user/s/skype/

This version was committed on 06-24-2008. Its version 1.7.113.22.2 while the previous version was 1.7.62.xxx. The Skype website still lists the old version, but this isn't accurate. If you update your Diablo it runs the new one.

One might have success using the application on Chinook.

BTW, it really pisses me off I can't uninstall the l10n packages. I hardly speak any of these languages...
