Read from Simon that App World is rumored to launch in Italy July 20th. I have heard that it takes RIM legal at least 2 months to enter each new country so it could be as long as 4-5 years before we see all the major European countries fitted with App World.
Make sure you get a notification about when App World is available in your language:
