Hold down on the POI, then go to view/edit POI and the tone will be listed. You can also add other cvs files from poi-factory to maemo mapper by using this online conversion tool http://www.poieditor.com/poi_convert/garmin-csv-to-gpx/ or GPSBabel http://www.gpsbabel.org/download.html I believe someone ported GPSBabel to Maemo, but I can't find it.
