Surprise, surprise when you stick salty water (your hand) in the way of your mobile phone signal then the signal gets attenuated.

So it’s not just the iPhone 4 that suffers from the death grip it is also the Droid, the HTC, Nokia in fact any mobile phone suffers unless the signal is so strong the attenuation becomes insignificant.

Haven’t we known this for years, or has the whole world fallen over and banged it’s head.
