GPRS connection and threads

Target: store an used IAP to the config file and reuse the same connection next time without user interaction.
Common question but with a trick.

IAP storing part is implemented like (pseudocode):
  sockserv.Connect();
  connection.Open(sockserv);
  connection.EnumerateConnections();
  connection.GetConnectionInfo( 1, inf );
  store( inf()iIapId );
I end up with some number in conf file.

Next time I want to avoid user interaction, I do:
  TCommDbConnPref connectPref;
  connectPref.SetDialogPreference(ECommDbDialogPrefDoNotPrompt);
  connectPref.SetDirection(ECommDbConnectionDirectionOutgoing);
  connectPref.SetIapId( setup.GetInt(SETUPKEY_UI_IAP) );
  connection.Start( connectPref );

But, the tricky part - the socket creation/connection takes place in another thread. And this thread asks for an IAP again ignoring the fact that there is a GPRS connection up and active already.

Do you have any solutions?
