INS=STATUS + car reset question

Hi List, I'm running into the following command sequence in a Nexus One Android 2.3 phone: C-APDU:80F20001FF (STATUS) R-APDU:6C12 (Incorrect Parameter P3) After which the phone power-cycles the card. I'm wondering whether this is is desired behavior, or if it's a bug in the new MITM code. Phone seems to reset the card quite often when in USIM mode. Running the card in SIM mode, this doesn't happen. Cheers Tom
