An interesting bit of information: on Tuesday afternoon, to the extend that
cellphones operated, GSM encryption was turned off throughout Manhattan. My
GSM phone would repeatedly warn me of this on every call I made (or tried
to make). As of Wednesday morning, things were back to normal.
Does anyone have more details on this ?
