I'm mapping using a Nokia N95 with NmeaInfo.
I've contributed for NmeaInfo a build of LocationRequester that support Python 1.4.x with a bugfix for correct display of km/h speed.
NmeaInfo is running with Python 1.4.1 on my N95 with firmware 20.0.015. Memory management of newest firmware give a lot of improvement in memory management and battery life, so I can keep NmeaInfo running in background using other navigation software.
The GPS embedded in N95 use LBS API and allow you to use more and more applications that make use of gps at the same time without third part bridge software. It seems to me quite precise but sometime take too much time to fix.
Where i'm mapping
I'm mapping near Venice and the nearest area of Treviso and Padua.
