Onan, A Cinema owner in Ireland Purchased such a device for blocking Cell Phone transmissions. He was forced to turn it off as he was advised he could be prosecuted under the same law as they used to use for Radar Detectors in Cars, The RadioTelephony act, which I believe is very similar to its namesake in the Uk.
I think they are a bloody good idea. Cell phones are becoming so Antisocial. Peopla actually start talking on them in the cinema over here in the US, not even making the slightest effort to hide the fact
