[maemo-developers] How do I get my own phone number?

[From: Wolf Geldmacher]

Hi list,

For an application I want to write (theft prevention) I need to know the 
current phone number of the device (or - if that is not possible - some other 
means to uniquely identify the SIM currently inserted).

Is there a way to get this information?

I've searched the docs & the website for an answer but cannot find one - maybe 
you can help?

Regards,
Wolf
