Hello,
I am thinking of doing a demo of blue snarfing / blue bugging or some other bluetooth attack for my networking class project.
I currently do not own a bluetooth phone to attack. Does anyone know what phones a most vulnerable to these types of attacks and if it is possible to get them cheaply on ebay and attack them without actvating them with phone service?

Thanks

ps I would be doing this demo right next to my computer so do you think I could just use a BT100 without any external antenna or anything to do this demo?
