Yeah I'd definitely recommend Viigo, Poynt, Google Maps, possibly Weatherbug, and YouMail - all of which are working perfectly on my Tour right now. Also, try plugging your Tour in to your Desktop Manager to see if any updates are available - did this on mine and it already had an update for it yesterday!
The VZW rep in store said they added Visual VM to my account, but MyVerizon shows that it's not on there. Yet I was able to download the software and access my VM as it should. Wonder what's up with that...
