Hello Scott,

I'm sorry to say that you're out of luck. The bluetooth hack you saw on youtube using a 770 is actually an exploit of an error in older Nokia S60 phones (S60 platform 1 and 2) that allowed serial connections without prompting the user for accept or passwords; other services as DUN were protected, but by issueing AT commands the attacker could obtain various information from the phone, as contacts list, or make the phone do stuff, like calling a number or sending an SMS. The preffered way of attack was making a call to a premium number.

I don't think you'll find such phones still in the wild (they're pretty old for cell phone technology after all).

I'm not aware of bluetooth vulnerabilities in more recent Nokia phones or in other cells. You can try search the net.

It's important to say that the 770 is just a convenient portable computer with bluetooth, and not necessarily required to perform the attack. The attack can be run as well from a laptop, or any J2ME phone running the good attack program.
