This is off topic from the boot time of a Touch Pad, but, Rockbeast, you are doing it correctly and it IS what the Flight Attendants say.

I am sure it was due to lawyers and finances and potential liability, but we were unable to find a single company willing to join us in future research or that had done any actual previous research or would share what they had done. Yet, ALL phone manufacturers & ALL aircraft makers recommended against allowing ANY use of phones--even on the ground. I have no idea if this came from their safety/tech ops type people, from their lawyers or a combination. BUT, they were unanimous (individually) in their recommendations.
You may remember the old days (some airlines may still have this) when there were phones built into the back of the seats and you paid by the minute. These phones had been tested and had specific shielding to protect instrumentation in the flight deck.
In our individual airline testing, we found some instrument anamolies when we brought & used some Crackberries into the flight deck, but we couldn't get anything consistent/scientific results.
As a result and due to the competition, a compromise was reached--use would be limited to above 10,000 feet, a supposedly less critical time. From the flight deck, we signal the flight attendants, and they make the announcement, "We are now at a safe altitude..." For our planes that have wi-fi, we have it set to automatically turn on and off at 10,000 ft. Some airlines have different indications (lights activated by the flight deck that say electronic devices may or may not be used), others have new shielding, etc. (typically foreign airlines at this time) that allow for more extensive use of phones.
As for Martin being worried about flying into someone else's jetwash, that isn't as major a worry to me as we usually have the expert Air Traffic Controllers maintaining appropriate separation between us aircraft, BUT, in major airlines, we also fly Category IIIb approaches in the fog. The ceiling (cloud base) can be ZERO feet and the forward visibility can be as low as 150 ft, though I don't think I have accomplished one w/less than 300 ft. This approach requires the plane, the airport and the crew to all have special training/qualifications and currency. It would be nice if the phones were off, as asked by the Flight Attendants as well.

I am not naive. Even w/the best of intentions, we have all left our phones on and the odds of causing any interference to a flight is minimal. I do, however, appreciate Rockbeast's respect for authority & wonder about all in this thread who seem to think they are smarter than the phone and airline manufacturers as well as the FAA and individual airlines.
You may be smarter, but hopefully, I have shed some light in to the history of airline mobile phone policy & why it may be important. Sorry if turning your phone off causes you a couple minutes of inconvenience while we taxi to the gate. What was life like before cell phones???
