Does anyone know what are the network security policies used in Nokia's J2ME/MIDP enabled phones? Are network connections from a midlet limited to the midlet's originating server (and port) only or is it possible to connect to any server (and any port)? In my tests I have found that this varies from phone to phone but I'd like to know what the security policy really is (or at least what it is supposed to be). How does this work for a midlet that has been downloaded via infra red as it has no originating server? It cannot access network at all?
