I do that quite a lot with the Google Maps on my Nokia when I’m travelling. I’m glad I’m not the only one (!)

Any ideas why mt iPhone (1st gen/OS 2.0) is so poor at geo location with cell sites??

Hactually Mr. Cridland, I took my TomTom (on a PDA with bluetooth GPS receiver) on a train once, out of Birmingham Snowhill…

(… What I’m about to say is really sad and indicts me as an out and out geek, but never mind)

From how TomTom was behaving, I guessed that the algorithm it uses to average out the GPS information rssulted in it trying to make my path jump to the nearest road, but once I was on the train going at speed and out of the inner city, it just followed the path of the railway line (which was marked on the screen) fairly accurately. Lost the signal a few times but on the whole it wasn’t too shabby. :)
