Is there anything actually dangerous about cellphones?

Such as electromagnetic fields or something similar.

All of the credible evidence so far indicates that cell phone use is not harmful to humans. However, there are some political organizations (like the UN) who are taking a cautious approach and calling for more research just to make sure. Cell phones communicate to cell towers using ordinary radio waves, like the kind that are constantly raining down on you from distant galaxies. Low-power radio waves are not harmful to humans. In general, radio waves do not have enough energy per photon to cause cancer via ionization.

UPDATE: The OP specifically asked about "electromagnetic fields". Obviously, cell phone use can distract you while driving and cause harm that way.
