are there are restrictions on which ports a midp application can communicate with, particularly on at&t wireless' network? i'm testing an application that communicates on port 8080. it works fine in the nokia 7210 emulator, but not when it's deployed to the phone. on the phone, the "G" and lock indicators appear, but there is no indication of a request coming in from the phone. any ideas what might be causing this?
also, is there a restriction that the midp application cannot communicate on a different port from which it was downloaded from? i downloaded my app on port 80, but conduct normal application data transfer on port 8080...
side question, what does the lock indicator mean when accessing the network? is data encrypted between the phone and attws's gateway?
last, is it possible to transfer data over SSL from a midp application? if so, is it simply a matter of getting an SSL certificate and connecting to "https://..." from a midp application?
