Discovery of Bluetooth idents on cell phones

I scanned for Bluetooth identities in a public house (a bar in Canary Wharf in East London, UK). I found all these phone indentities advertising themselves. I guess this is legal, but now I have taken photographs and placed them on the web...

And I breaking the law in the UK or elsewhere??

Nokia has admitted that some of its Bluetooth-enabled mobile phones are vulnerable to "bluesnarfing",
which is where an attacker could read, modify and copy a phone's
address book and calendar without leaving any trace of the intrusion.
