I have only once owned a mobile phone, a Motorola M301, about 15 years 
ago. I was very worried by the way it would heat my face up during use, 
and seemed to make the backs of my eyes feel hot as well. I dumped it 
after about one year of use and have lived happily without one ever since.

The only rigorous sources of info on the bioeffects of man-made EM 
radiation I can suggest are:

* Dr G J Hyland (one of his early reports can be seen at 
http://www.iegmp.org.uk/evidence/hyland.htm - Google for his other 
papers elsewhere)

* Powerwatch (http://www.powerwatch.org.uk/) : "Powerwatch is a 
non-profit independent organisation with a central role in the UK 
Electromagnetic Field and Microwave Radiation health debate."

I understand that it's not necessarily the carrier frequency that upsets 
biological life, rather it's the modulation scheme and spectral content, 
which can give rise to epilepsy, sleep disruption, stress etc.

It's a very interesting subject and I hope it could lead to a lot of 
employment for engineers seeking to communicate and distribute power in 
ever healthier ways.
