Mumbo-jumbo
There was quite some coverage here in Belgium, and just about every expert said it was rubbish and even if it wasn't, cellphones would detect a worse signal and start to increase the power of the signals they're emitting, rendering the whole thing useless.
And the quantum thing would be totally irrelevant as normal physics apply to cellphone signals (I say 'would be' because I'm no expert, I just read it somewhere, then moved on to my evening of mind-numbing TV).
