I just ran across this article linked from Blues News that tell the quick story of some iPhone fan boy who decided that his iPhone was providing better information than the pilot and the people on the other end of the pilot's comm line.
Long story short, the pilot said there was a delay because of rain, the passenger looked up the destination and saw no rain, asked a flight attendant to ask the pilot what the real problem was, pilot replied over the intercom directly to the iPhone passenger with the following
"If the passenger with the IPhone would be kind enough to use it to check the weather at our alternate, calculate our fuel burn due to being rerouted around the storms, call the dispatcher to arrange our release, and then make a phone call to the nearest Air Traffic Control center to arrange our timely departure amongst the other aircraft carrying passengers with IPhones, then we will be more than happy to depart. Please ring your call button to advise the Flight Attendant and your fellow passengers when you deem it ready and responsible for this multi-million dollar aircraft and its passengers to safely leave."
Head over to Plane Buzz for the full story. Gotta say, this coulda happened with any internet ready phone, but it is rather funny that the iPhone got dragged into the center of this story.
Side note, I just finished jPod and plan on posting a review in the next day or so...so stay tuned.
