I admit that I wait until the very last moment to turn off my beloved Palm, but I do have it off during the flight.

NYT: Why phones can interfere with flight safety - Travel - Business Travel - msnbc.com

I heard some buzzing in the headsets the other night in the sim. The other pilot and the IP said it must be someone's cell phone going off. I've heard others on here say that they can tell. I try to follow the rules the best I can.

We are still a nation of fear in many ways though in my opinion.
This is the type of person who worries about the next asteriod or if the apples he eats each day really have enough Alar on them to harm him. Never mind that the amount of Alar required to produce those results was staggering:

Radio gasket? Think he meant shielding?

Interesting but dated read on foreign carriers that allow cell use.

The gasket is in place to keep all the magic smoke inside the radio.

I can neither confirm or deny at this conjuncture whether or not airline pilots have ever left their electronic devices turned on in their flight bags for an entire flight with no adverse affects.

Not just pilots.. passengers too, as the article says. Its not just forgetting to turn them off. Its ignoring the instructions. I think a lot of passengers don't believe there is a real safety concern. They're probably right. Otherwise, we'd have planes falling out of the sky on a regular basis. Proving the link wouldn't be difficult at all.

Anyone see the Myth Busters episode? Well, its a TV show made for entertainment, I know. But they went to great lengths to try and create interference on a Falcon 2000 (if I remember right). They didn't totally debunk the myth.. but their result was similar to a common maintenance entry.. "Unable to duplicate malfunction on the ground."

An old style analog cell phone used in the rear of the CRJ-200 can trigger the cargo smoke caution. There's no way to access the cargo bay in flight, so it's mandatory bottle-blow and divert to nearest suitable. Maybe not a huge safety issue but certainly an inconvenience and waste of tens of thousands of dollars (the bottles are not cheap).

To make matters worse, the analog phones would actually work in the flight levels, but not sure if anyone even uses those anymore.

Well, that may be. And I have heard a cell phone going off through a buzzing in the headset.. USMCFLYR touched on that. But I'm skeptical about the risk to safety. Boeing concluded in their own study..

"As a result of these and other investigations, Boeing has not been able to find a definite correlation between PEDs and the associated reported airplane anomalies."

Correct me if I'm wrong here, but the use of cellphones on aircraft is not prohibited by FAA regulations, notwithstanding a company's GOM. It is an FCC rule.

True, but remember that my personal experience that once was in the simulator, and I didn't even recognize it for what it (supposedly) was. My sim partner and the instructor each said that someone's cell phone in back must have been going off.
