polite mode:
1. not connected to any internet - auto connects and sends from any connection

rude mode:
1. auto connects only if connected to wifi but not when connected to gprs. if the device is already connected to gprs would not connect. tells no path found for apn please check settings.

havoc mode:
would not auto connect at all on any type of connection you have.

and after you send an mms from any of the modes above and receive and try to open the app fmms it auto closes. only reboot seems to fix that.
