Hey thanks for taking the time to make the comment. What you say makes very good sense.

Read the tech specs on apple's site. Top right it says environmental conditions "maximum operating altitude 3,000 meters/10,000 feet." I'm not joking. go look.

Most long distance flights fly around 30,000 ft/10,000 metres (that's 3 times higher than apple say you can use ipod touch)

Also I'll say it again, FAA rules state that you may not use a device that contains an antenna on a flight unless the antenna can be turned off and you may not switch the antenna on for the duration of the flight. (Have you noticed the switch on your laptop that does exactly that?)

So unless the iPod touch has a "wifi off" switch (and it seems unclear to me at the moment) you can't even power it up on a plane.

Now I'm aware that many aircraft pressurize the cabin to be effectively at a lower altitude and that may have some bearing but again, this is unclear.

So sorry thetinguy but I'm respectfully gonna take your assertions with a pinch of salt.
