OMG! WHEN I LICK MY FINGERS AND STICK THEM InTO AN OUTLET iT HURTS
You're actually comparing that to holding a cellphone in a wet hand...?
People are conditioned to cellphones being plastic and safe to hold when-effing-ever, and I guarantee you that right this minute there's about 3,000,000 people out there in the world picking up their cellphones on the beach after a swim, surfing the web in the bathtub, answering a call holding the phone against wet hair because they just came out of the shower... it's not on anyone's map that they would receive a shock from a damn cellphone. They know not to bring it with them while scuba diving, but apart from that, anything goes. And sometimes people need to make emergency calls in horrible situations where they have more critical things on their minds than looking for the nearest butler ready to hand them a dry towel.
But whatever, I'm looking forward to stories like "iPhone short circuited my grandmother's pacemaker" and "iPhone 4 proven to be world's most efficient lightning rod - user incinerated after attracting flash from thundercloud 6 miles away".
The only issue was vanity and pocketability. People don't like cell phones with antennas. it's that simple.
Well, looks and pocketability are obviously part of it but there's also SAR ratings to consider. Manufacturers don't want to hear that their products are veritable microwave ovens that cook people's brains, and the FCC (and their equivalents worldwide) make a big deal about the antenna's proximity to the brain. That's why antennas these days are usually located at the bottom of the phone, behind the microphone. For a while there (before antennas became internal) it was popular to put a stubby antenna at the top and those obviously got poor SAR ratings because the tip of the antenna was just above the ear. Since an external antenna that sticks out at the
bottom of the phone would be incredibly inconvenient and stupid looking, they did away with external antennas altogether once the whole SAR rating thing took off.
