I think the rule is bogus. Almost as bogus as my being reminded it is against federal regulations? to use the first class bathroom directly across for the coach bathroom. Fortunately I didn't see the sense in arguing a point that had the potential to be arrested when I landed but goodness... It was tempting.
Got a tip for us?

That made me laugh out loud! (I'm quite bald!)
You're right, tho, a lot of over-egoed twunts out there.
That one is a post-9/11 thing, more about having folks congregating near the flight deck, and less about whether or not your "worthy" enough to use the FC lav. Does seem silly, though, when you're in the first row of coach and get told to walk back 125 feet instead of forward 15...
Then you have a lot to learn because if they are not designed to that then you care to explain why the phone works holding in any direction. Hold it upside down and guess what nothing makes it to the tower. So where the hell do you come off with crap like that. It would take the same amount of power to make one that goes in all direction as for one direction with out a something to bounce the signal off of but guess what phones lack that.
Add to that fact that is not now the waves go out from the phone....
Yes range is limited but you get HUGE increase when you remove everything between phone and tower.
It takes simple understanding why radios work. If you drive farther from a city and you notice how a car radio gets statice and cuts in and out as you go up and down hills. Same principle. Just you are so high the earth is not an issue.
note completely. The phone can screw with ground to air commincations if the shielding on the plane is ever damage a little.
GSM phones are the one that can screw it up. Reason for it is the feq. they run at is in human hearing range. Proof of this is take GSM phone and set it next to some speakers and call it. You will noticed a strong buzzing sound caused my the phone. Now CMDA phones operation and a much higher feq out side of human hearing. So while they will put a buzz though the speakers it just will be to high for you to hear.
Remember your phone is nothing more than a fancy two way radio.
Don't care about the technical side of this argument.
People that use cell phones in a closed environment, like a plane, except in an emergency, are rude, ignorant, self-absorbed and don't give a **** about other people's comfort.
End of discussion.
PS: Stop drivers from using them too, even hands-free. It steals attention from the job at hand.

I did not know that about how the can screw up ground communication. My thought was there was a crash some time ago that they couldn't determine the specific cause which then resulted in the ban of cell phone use. I do agree I don't want someone next to me chatting the entire flight.
Aside from admitting that I should have said cell phone tower antennas, nothing else changes, and everything in the post was factual, accurate, and based on this universe. I've dealt with it professionally for over 20 years, and know a thing or two about RF propagation. Believe what you want, but physics is physics. The ARP of a cell tower radiates horizontally, to the horizon & below. Any radiated energy above the horizon is unintentional and wasted, and not in the best economic interest of the provider, particularly when the maximum allowable output is fairly strictly controlled by the FCC.
OK, now that's just silly. Human hearing is roughly between 20Hz -20KHz. Cell phones operate in a few different bands, the lowest of which is 850MHz (and go up from there), or over 40 thousand times higher than any reasonable human perception. What you hear is EMI/RFI between the phone and the speaker caused by the oscillations of the various internal circuitry of the phone, generally between 3000-8000Hz (and at that, you're likely hearing a harmonic vibration, not that actual oscillation).
Please, study the technology a little.
does not change the fact only GSM phones are able to produce that problem. CMDA operate at a much higher feq than GSM phones and tend not to cause the buzzing problem.
