Russian Theatre Jams Mobiles

Yes, finally someone has gone and done it! And that someone is the manager of the Alexandrinsky Theatre in St. Petersburg. Fed up with the lack of consideration shown by mobile phone users during performances, the Theatre has had installed a phone jamming device that thankfully ensures there's no chance of Crazy Frog interrupting Chekhov.

Wouldn't it be great if all theatres and cinemas followed suit?
