I have a standard cell phone right now, and of course there's been a lot of discussion of the potential dangers of cell phone use. Right now, I keep my cell phone off at all times unless I am texting or talking.
I have been considering switching to a smartphone, an iphone in particular, and my understanding is that these phones have even higher emf levels.
Are there any devices which can protect cell phone users from emf's?
A quick search brings up a product called sar shield, but I know of no research on it's effectiveness.
