I use smartcard reader for this.
I recommend http://nobbi.com/download/SIMspyII.zip for PC/SC readers (Towitoko) or http://www.endorasoft.es/download/xsim.zip for smartmouse / phoenix based readers. You should find PC/SC Reader at most Computer-Shops.
Remove the Batterie from your phone, and read Kc from Sim-Card (Don't Switch off Phone or Kc will be deleted from SIM)

Hi all,
Does anyone have any suggestions with regard to models of phone in which it is easy to view the current Kc? I have a Motorola C115, Nokia 3310/6630, Android Desire, iPhone etc. I can get every everything from the in built field test modes, however I really want to get the current session key so that I can verify/analyse my captured bursts.
Thanks,
Matt.
