>As the phone periodically reports the signal strengths of surrounding cells for the purposes of handover just taking a glimpse of this is enough to triangulate well. Not when the phone is idle and is not leaving a location area though. (At least that's my memory from my college class)

In GSM there is some periodic communication even in the idle non-moving case, but the period is on the order of hours.
