It amazes me that criminals are daft enough to use the same phone all the time. You can buy a new phone every day for not many quids and no one would ever trace you on pay as you go.
Not a bad investment for a multi million pound scam.

I know computers can use this technology but how does it work and also, can it track where a cellphone user is?

Ok, dear, I won't keep tracking your phone anylonger!  []

Which is why the UK government now insists you show ID when you buy a mobile phone (part of their anti-terrorist legislation).

Ofcourse, that does not stop you from buying phones on the black market (probably stolen phones).

"Triangulation?
That would rely on accurate direction finding antennae in each cell - to get the 'angles'."
No you can do without the angle data if you know the distances. You can gaet that (badly) from signal strength or quite accurately from timing data (which is how GPS works).

Maybe but do they actually do it?

Anyone can request spare sim cards, in the UK. All you need do if contact say t-mobile and ask for payg sims to be sent to your home.

they will then send you two, and not bother to check that the person they are addressed to lives at that address, i know i have just done it.
