I've heard the ban on cellphones during flight was actually something pushed for by the cellular companies. Supposedly it was too difficult to keep track of the roaming issue whilest up in a plane, so that would have thrown off their billing practices. Don't know if that's true or not, but as mentioned above, apparently it doesn't interfere with actual pilot-ground communications. Admittedly, it's also nice not to be stuck next to a cellphone yakker for 6 hours straight. Don't know about the rest of the electronic devices and their purported interference, though.
