OS 4.5's geotagging option in the camera settings works great (although i think that the little satellite icon - bottom left - is wrong because it always has that red X there even when sats are available - prob a bug).
also BBplaces is GREAT !! (because you can use it to upload etc) - try it !
- like prev. posts mention -
ALSO i really like/recommend GPSed.com .. because it uploads your gpx trail (or trip log) on line (every minute if you want to) .. GREAT STUFF !!
