If you are really worried about this, I recommend surgery.
Me too -but in a more literal way.
Sorry for the downvotable comment, but cannot resist a pun, especially when it kinda makes my actual point.
The thing is, whether the MBP is "always listening" or not is of little consequence, in an age when we know that governments look into the wires, have taps into ISPs and can listen to any and all mobile phone conversation.
Btw, my iMac 27" 2009, doesn't seem to register any sound with the internal mic set to the minimum volume. And there's also the "Audio MIDI setup" program, where you can disable it completely.
GSM uses several cryptographic algorithms for security.
The A5/1 and A5/2 stream ciphers are used for ensuring
over-the-air voice privacy. A5/1 was developed first
and is a stronger algorithm used within Europe and the
United States; A5/2 is weaker and used in other
countries. Serious weaknesses have been found in both
algorithms: it is possible to break A5/2 in real-time
with a ciphertext-only attack, and in January 2007, The
Hacker's Choice started the A5/1 cracking project with
plans to use FPGAs that allow A5/1 to be broken with a
rainbow table attack.
