Help understanding capabilities of bluetooth recievers

I've yet to dive into the world of bluetooth devices for the arduino but I do have a specific question:

Will the Xbee (does it matter the model?) provide the ability to scan and/or recognize bluetooth signal from cell phones?

Simply stated I'd like to know if I can see what devices are omitting bluetooth signals around me. I imagine simply discovery would do this but unsure if the hardware and software available for the Arduino would allow this capability.

Will the Xbee (does it matter the model?) provide the ability to scan and/or recognize bluetooth signal from cell phones?

Since XBees are not (all) bluetooth devices, the answer is no.

Ok, are there ANY bluetooth devices (xbee or not) that can do what I am asking?
