So this is fairly interesting... And perhaps it was already reported... But in Blackberry World, in the music and video sections of My World, there is an option to refresh the view. And the icon for this action is a little cloud. Could be pointing to things to come.
Edit Dec. 14: The cloud appears again Anyone speak thai? What is the third icon across the top row?
This may point to being able to purchase movies/music online from a desktop app or browser, and then syncing it from the cloud to your device. Just a curious icon for a "refresh" command is all, a cloud with an arrow coming out of it...
