Last night I noticed this new version of wififofum.
Version 2.2.8 Released 19th April 2007
* Null characters removed from SSID in the name tag in KML exporter, Google Earth needs this.
* Lat/lons in the exported file formats now use decimal points for all regional settings. This is required for Google Earth.
* GPS performance improved and you should see less CPU utilisation.
