All cellphones now have the GPS feature, but NOT all towers have the
technology to triangleate.

GPS is different from how mobile phone positioning usually works. GPS
uses about 30 satellites on the orbit and is very accurate, but very few
phones have a GPS receiver.

Cell phone positioning is usually done by measuring the distance of the
phone from at least three different stations. I don't think it requires
any special support from the handset, so it works with any phone. It's
not accurate at all, but can help on emergencies.
