I bought some EM radiation blocking cloth from LessEMF and stitched it to the inside pocket of my jacket which I rarely use. If I'm feeling paranoid (or if I'm not arsed to turn on airplane mode to save battery) I just put it in that pocket instead of the normal one and zero communications can get in (especially my mother)

curious. Do you notice decreased battery life if you do this? I would think you would chew through battery like a mofo if you block carrier, but leave the phone on. It's gonna try hard to hit a tower non-stop, I expect.

My phone does. If I ever take it to an area with zero reception and forget to turn on airplane mode, the battery dies in 2-3 hours.
