Buried away in the comments and the inevitable discussion of property rights on this post about the iniquities of mobile phones at Samizdata.net is this beautifully simple idea.
Maybe they need to introduce a Friendly "quiet" signal, not a jammer, so that when detected it switches to a non audible ring? Places such as conference centres, meeting rooms etc, would have these very small transmitters that send the quiet signal.
This would be an excellent addition to future mobile phone standards.
