Adobe Flash Lite for Nokia 5800, that gives you access to high quality videos and enables rich content on the web to be played on you phone, has just got an update to the version 3.1.4 from its previous version 3.1.
There has been no changelog of the version 3.1.4 on the web as yet. Therefore we would have to wait for a little bit more for the official changelog.
However, to update the Flash Lite on your Nokia 5800, Just open the built-in App update (Menu -> Applications -> App. Update) on your phone and select Adobe Flash 3.1.
