If you read the linked article, they find "...sensitivity to low-level radiation to a subtle degree...". Except they strapped cell phones to users' heads. Given that cell-phone radiation falls off at a factor of 1/r^2, I would imagine the effects disappear very quickly as the cell phone gets further from your head. Also, the 2nd study used 10 sleep-deprived men. That's a pretty small sample size.
