So I've been to a few health seminars with my mom recently, and one of the doctor's was really stressing the subject of electromagnetic interference and its longterm effects on the body. Well, one particular research group has gone so far as to claim the iPhone to be one of the most dangerous phones of today. Check this out: Blue Tube Headset - Help Keep Harmful Cell Phone Radiation Away I understand that the Specific Absorption Rates (SAR levels) for the iPhone are as follows, with the maximum rating set by the FCC to be 1.6W/kg *iPhone*: 0.974 *iPhone 3G*: 1.388 *iPhone 3G S*: 1.19 Cell Phone Radiation Chart - Mobile phone EMF safety shield Is Mercola's advertising for the BlueTube just a bunch of BS (because the marketing seems very superficial) or will I be fine talking on the iPhone 3G S over speakerphone (which I do 90% of the time on the 3G already)? My mom has gone paranoid over the entire topic of EMI exposure and brain tumors. That said, I'm interested in your replies, thanks in advance.
