The phone I was using is an Ericsson T39 ("world" model). Of course, it
was using the 1.9G band (nothing else is available in the US, AFAIK).

Most of the day I was around 116 Street (Columbia U. campus), but at around
7pm I went to West 4 Street (they hadn't closed that part off yet), and the
problem persisted.

Just to clarify -- the phone was working, but the encryption was off (I suppose
that could be classified as "not working" :-)
