yeah, there was a post about some apps, thinking they're touch screen apps. I do think the google youtube app was one. Try out the Vision for Youtube, until / if they ever port the app to the tour.
You could also try Xenozu (sp?). Works on the 8330 and 8830. You probably won't find it in app store (even though its there) because my 8830 could find it, my son's 8330m couldn't. Appworld issue.
