I made the script more interactive but you can of course change it so that it accepts arguments instead. Just use python's sys.argv. If i have the time, i will change it so that it can support both.

Also, if anyone is interested, i have made another sample script listens to incoming messages. I placed the link in the pymaemo wiki:
http://wiki.maemo.org/PyMaemo#Examples or you can also read it directly here: http://www.paraiso.dk/incomingsms.txt
