Flash Lite 3 introduced a new security model which is not compatible with previous Flash Lite players. It means that if you have a Flash Lite 2 application, that need to connect to the internet, and you try to run it from Flash Lite 3, the application will fail to make the connection.
On Forum Nokia Flash Lite WiKi there is an article describing this issue. Adobe released a tool to fix this problem: Local Content Updater.
