Receiving, Decoding and Decrypting GSM Signals with the RTL-SDR
A while back we did a small write up on receiving and analyzing cellular GSM signals with the RTL-SDR. Now blogger Domi has taken it further and has done an excellent big write up on his blog showing how to receive, decode, and also decrypt your own cell phone GSM signals with the RTL-SDR.
Domi’s big write up is split into four posts. It starts with an introduction to GSM, then focuses on setting up the environment and required software, then uncovering the TMSI (step to be released later), and then finally shows how to actually receive and decrypt your cell phone data such as voice and SMS messages.

which is obviously illegal. any kind of tutorial of how to tap and decrypt your ‘own’ phone`s voice calls is nothing but a stepping stone to perform it against another person, which IS illegal.
