Hmm so even if you can ever buy a secure phone you trust, you need to put another, completely opaque, computer into it to make it function (on cell networks anyway.)

I wonder if there’s any easy way to make a private GSM network so that we can see what data is actually passed between the SIM and the tower?

There is, Osmocom/OpenBSC. IIRC they got 3G working in a fully FOSS stack.

They have a private GSM network at the CCC conference in Hamburg every year. Sim cards go for 2 euros (or you bring the one from last year) and it allows you to call anyone anywhere for free (for the duration of the conference, and you need to get a signal from the conference building of course). No GPRS or anything like that though.

But the SIM card can't actively do anything to your stuff, can it? It has to defend itself from you, not the other way around.
