I know, but it's just another part of the "old world" slipping into history.
But remember according to the tobacco companies, cigarette smoking doesn't cause cancer. So if the phone companies say cellphones don't cause brain damage.......
things that make you go hmmm.......
Yes, but...
The frequency ranges are higher, allowing them to pinpoint more.
A wave at say 1900 Mhz, is a much more concentrated wave, than say 840 Mhz.
Theoretically speaking, the danger increases, as the wavelength shrinks. A larger wavelength (lower frequency), spreads much farther out, and therefore doesn't target a small section of tissue.
Just my thoughts -- YMMV depending on the amount of tissue left inside yer head
