I could not find code for service(s) that replies to these DBus messages and actually accesses the SIM card.
I know the first link - it's a generic description of the API between ME and the SIM, but AFAIK this is unusable as this is 'hidden under the cover of Maemo'.

Thanks for the two other links - they're interesting, but AFAIK there are no d-bus messages for communicating with the SIM (OK, there are some messages to access contacts etc. but not those we need).

So either someone (Nokia?) has to add those d-bus messages, or we need to access the SIM in a different way. Or maybe I'm completely wrong
