A comment on $15 phone, 3 minutes all that's needed to eavesdrop on GSM call.

I wonder if one could crack it even faster with more than 4 phones sniffing. Maybe 8 or 16 phones? You could easily fit those in a backpack, along with a 2TB external HDD. Assuming the sampling rate is the bottleneck, you could maybe get down into the sub-60second range with a few more phones....

Amazing stuff as usual from the CCC!

no, more phone wouldn't make it faster Also, having the hdd with you is really not required, you can just use a beefy external server you ssh to via a 3G data connection or something.
