Idea: SIM emulation

[andrew_sh]

I came up with the following idea. Please tell me what you think about it.
Let's say you have the imsi and ki codes of one or more sim cards. Wouldn't it be nice to use the phone with no sim inside?
This would mean that the sim driver would need to redirect input/output to a custom app which would emulate a green/silver card.
I have programmed apps for the pocket pc but this is way out of my abilities.

I would appreciate some comments

Impossible I'm afraid. The SIM card holds something called the Ki or Authentication Key that is impossible to retrieve using a smart-card interface.

The Phone actually sends data to the SIM which is then cryptographically signed with this key as part of registering you on the network.

Thanks for the input but this won't be the problem.
Mechanisms exist that can extract the necessary codes from comp128v1 sims (imsi and ki).
This is how sim cloning works.
I already have these numbers of my sim card and I can already duplicate it.
You only need a card reader, no expensive hardware

great idea, hasn't the windows mobile sdk something similar?

Absolutely impossible. This would require radio hacking which requires lots of time, and would be device-specific.
