Correlation EMF / DNA
The best papers I have seen on the subject are this:

And if you look closely at the chart you'll see this:


If your are really concerned about radiation, you should stop eating banannas, not be concerned about cell phones. 

Your body also generates antimatter:


  When Potassium-40 decays, it releases a positron, the electron’s
  antimatter twin, so you also contain a small amount of antimatter. The
  average human produces more than 4000 positrons per day, about 180 per
  hour. But it’s not long before these positrons bump into your
  electrons and annihilate into radiation in the form of gamma rays.

So why doesn't everyone get cancer? Because your body can stop cancer in dozens of ways and repair DNA.

The next one is this:

If cell phones did really cause cancer in humans, then you would have seen the cancer rate go up substantially. The last thing is, people are wierd when it comes to cancer, because they don't understand how it works and they hate the unknown. 

These two charts show conclusively that cellphones do not cause cancer.

EDIT

Just to re-iterate the cancer chart, if you look at the CDC brain cancer rates have not gone up since the advent of cell phones. I would expect that if cell phones did cause brain cancer, the rate would have gone up mirrored with the rate of cell phone usage.
