An interesting thread on Google Answers, regarding what services are available to track the current location of a cell phone. (via del.icio.us).

For about $200.00 ICU, Inc. offers to locate a cellular telephone by
pinging the phone – a kind of triangulation process similar to the one
I mentioned earlier. Ms. Landers explained that the cell phone appears
as a ‘blip” on a screen. They provide the service 24 hours a day, 7
days a week in order to help locate missing persons, fugitives,
cheating spouses, etc. They regularly serve bondsmen, authorities,
investigators and many others. You will receive the results within 7
to 10 minutes of a successfully completed ping that will indicate
within approximately 50 feet, where the phone was located at the time
of the ping.

Aside from the cell phone tracing, the list of services on the I.C.U. Inc web site makes for fascinating reading.

Update: 08-15-2005 23:59 - Came across the CellTrack project, which is developing a free, open source cell phone tracking system (presently for GSM). It requires installing a client application on the phone, however, so it’s not useful for finding someone who doesn’t want to be found. (screenshots here)

Also came across this paranoia-inducing clip at Instapundit:

THEY CAN HEAR YOU NOW: When I was in Beirut in April one of the leaders of the Cedar Revolution, Nabil Abou-Charaf, told me that Syrian intelligence agents used cell phones to “spy” on people.

“You mean they monitor your phone conversations,” I said.

“No,” he said. “They can listen to us all the time even when we’re not using the phone.” He could tell I didn’t believe him. “We know as a fact they can do this.”

Still, I didn’t believe what he said about spies using his cell phone as a bug. If the cell phone is off or just sitting there it isn’t transmitting a signal.

Looks like I was wrong. Julian Sanchez at Hit and Run points out this chilling excerpt from a story in last week’s Guardian.

The main means of tracking terrorist suspects down has been the monitoring of mobile phone conversations. Not only can operators pinpoint users to within yards of their location by “triangulating” the signals from three base stations, but - according to a report in the Financial Times - the operators (under instructions from the authorities) can remotely install software onto a handset to activate the microphone even when the user is not making a call.
I’m sure the police love this feature. Police states apparently love it, as well.
