It would be great if we could get some information from the guys that did this at Defcon. Instead of having to completely re-invent the wheel, we can use their info and add to it. I searched the Defcon site and googled for anything relating to their project and found nothing. Anyone have contact info or a link for these guys? Thanks It was not an official presentation, it was a "party" in a room at the con. I remember reading an account of it somewhere, and how they screwed with a hooker on her phone.
