Nokia Sensor is a social software application from Nokia that allows you to meet similarly Bluetooth enabled Nokia phone owners around you. You can setup your own "folio" on your phone and then scan nearby phones to see other folios around you. Send sensor messages back and forth and view the ‘popularity’ of those around you. Check the Nokia website to see if your Nokia phone is compatible with the software, select your language, and then download for free the software application.
