Serious flaws in bluetooth security lead to disclosure of personal data... this is serious stuff... elsewhere i have read that *the* phone company already admitted this flaw...

btw, ed dumbhill has an interesting app with regards to bluetooth... that is registering your friend's bluetooth devices and associating it with FOAF or your address book and have the app monitor/scan the area... youll then be notified by the app that your friend or boss is in the area (assuming both have bluetooth enabled device registered in the app)... nice to use in conferences... planet gnome sure helps in aggregating blogs of some of the brightest open source developers nowadays... gnome rocks!
