Following this thread, I guess if a similar hack can be set up to allow a midlet accessing network without asking for user permission.

Maybe it's just a matter of ripping from kmidp20.zip file the classes responsible for HTTP security, hack them just like it has been done for SMS protocol, and let the network-accessing-midlet access to them.

Any idea about which class to look at?
