I suppose the high frequent emission of the cell phone simply messed up
the board computer systems. While these systems are pretty good covered
against HF emissions coming from outside - remember the Faraday effect
and look at the fuselage, made completely of metal - HF emitted inside a
cage can have pretty nasty effects. Also all the computer systems are
high frequency systems, and some of them run in the same frequence range
as the cell phones operate.
I vaguely remember an accident in Italy, also caused by someone who
thought, that safety rules on an airplane are only for poeple coming
from mars.

Good luck
