The most obvious reason not to perform a death grip on your iPhone is to prevent it from dropping your signal, but as the above video by Israeli software company Tawkon shows, there’s also a more invisible and dastardly effect: the death grip also causes your iPhone 4 to pump more radio frequency radiation into your brainpan.
It makes sense: when your iPhone 4 senses that it’s losing its connection to the nearest cell tower, it increases its radio frequency output to try to get a better signal. That’s true for all smartphones. It’s just how cell phones work.
As for whether or not you have anything to worry about by that radiation increase, no one knows the long term health effects of cellphone use, but me and Herb — the sentient, Kuato-esque goiter growing out of my left temple — say hell no. You cell phone hypochondriacs in the audience might want to start bumpering your head in tin foil anyway.
