Don't
forget you need a 
compatible cell phone !
Download on your computer the software 
and transfer it into your cell phone (it s free). Now
you should be able to communicate with the other Bluetooth
portable devices that are around you ( up to 15 meters
most of the time).
Now you can chat (messages are gratis) and
best thing is to record messages in advance : "Hello
dear Nokia 7610, is that pizza allright ? " or "
Sorry but i fear you just have been bluejacked..."
aso.
Have fun and be nice !
