Interestingly, some [early] models had external antenna jacks built in to them.

Many still have test jacks on them. Both my old Samsung A500 and my current Sanyo SCP-8100 have a connector (either MC or SMA, IIRC) on the back hidden under a rubber plug. My guess is that with an appropriate connector you could use, e.g., a pringles can to make your antenna much more directional. Triangluating on a non-isotropic antenna should be quite a bit harder... -- Riad S. Wahby rsw@jfet.org
