Good point Sculpin. Microwave radiation is a serious health concern. The closer you are to the source of the radiation the more danger it represents. Therefore it would make perfect sense to distance the phone from your head. Of course the only perfect earpiece is made by Sonomax.
Here’s more on the subject of microwave radiation:
“We’re all participating in a giant experiment in involuntary epidemiology — irradiated by cell phones and towers, cordless phones, satellites, broadcast antennas, military and aviation radar, TVs, computers, wireless internet, wireless LANs in schools and the workplace, and now these meters, waiting to see what it does to us.
Actually, we know what it does to us, so the results shouldn’t come as any surprise.
The main problem isn’t cancer, although the industry would like you to believe that, because then they can pull out statistics showing how infrequently it occurs as a result of low-level radiation. Cancer takes a long time to develop. Typically, other problems show up first: neurological, reproductive, and cardiac. Problems with severe headaches, sleep disturbances, memory loss, learning disabilities, attention deficit disorder, and infertility show up long before cancer. When cancer does appear, it’s typically brain tumors, leukemia, and lymphoma.”
