I'll stick to my academic studies:
What they
knew back then, was that radio signals were a largely unexplored fields. Now it isn't, and the increased knowledge has shown that many things we believed were partially exaggerated.
If I have to give you a scientific answer, I'll tell you that every single item in the world
is actually affected by
every single frequency of the spectrum. It's energy, after all :P you are blasted with energy, you are surely affected by it.
So, every piece of electronics inside an airplane is surely affected by mobile phones' signals. The point is that whatever the effect is, it can be ignored because it's too small.
At this very moment, my body is blasted and repeatedly hit by a million different radio signals, infrareds, x-rays from deep space, GPS signals, mobile phones all around me... yet I am fine
so is my PC.
It's not that hard to determine how an item is affected by the energy provided by the radio signal: you can measure the change in temperature, magnetic changes, increase/decrease of electricity, increase/decrease of frequency... once you determine that its effects can be ignored (technically speaking, the interference becomes simple "noise" which can be easily filtered by a band-pass filter if necessary), you're safe. If they can't be ignored, wrap it in gum cables or add a thinner-band-pass filter. If they still can't be ignored, use a thicker cable.
(I'm over-simplifying, of course)
And that's just the kind of tests that airplanes are undergoing in UK right now, for example. Nothing more, nothing less.

[And BTW, I'm not trying to tell that you should all go and use your mobile phones on airplanes. As Toxaris pointed out, it's not wise to piss off those who are keeping you in the air. I write this just so that if you happen to take an airplane and your neighbour doesn't turn off its phone, you don't die because of anxiety
