Object Push (Score 1)

Bluejacking relys on a couple of things to be in place to work. 1. Other end (jack-ee) has to have Bluetooth, and switch it on. Some phones come with it on by default 2. You have to agree to accept what your being sent, This can be worked around as you can set your Bluetooth devices name to be "Hi! you've been BlueJacked" 3. For the "total" jack experience OBEX Push profile has to be on either end, for the business card (vCard, same format as with IR on Palms etc.) exchange (when accepted(?) by the confused jack-ee) then they have a semi-permanent record on their phone. The ideas been around for a while, in singles bars (where techies lurk), and school playgrounds (where kids always have right ideas for mischief).
