Sorry for the crosspost; I just realized this is the proper forum.

How can I, as a third party jailbreak app writer (actually, from the command line would be best) get access to the current SIM's phone number? Is this even possible?

I'm cobbling together a trivial anti-theft tool for my iphone, and in case a new sim is plopped in, I'd like to be able to inform myself of the thief's phone number.

Erica Sadun's findme has helped with rough location; I'm just trying to plug other holes.

If you look in the address book, it might be in there.
