That may not be fraud- just stupidity.  Try an experiment: hold a phone
(cellular or otherwise) against your ear for 15 minutes.  Then remove it
and have a passerby touch your two ears and see which one feels
warmer.  I can virtually guarantee that most people will detect warmth
on the "phone side".  Make sure you hold it tightly against the ear!

It's the classical misunderstanding:  causality versus correlation.
The increased temperature would appear even if the user held a 
chalkboard eraser against his head.
