Cellphone Technical Question

If I leave my cell phone near my computer speakers I will hear occasional buzzing, clicking, etc. Before the phone begins to ring, I hear a dah..dah.daahhhhh. I know this is RF interference being picked up by the amplifier in the speaker. If one were to record this sound with a microphone at 11 or 22Khz, would it be possible to obtain any information (usable signal) from the recorded audio?
