I usually only travel a few times a year, however coming early January I have quite a trip planned and then some, plus have become addicted to "smart phones", those phones that do everything and some calls on the side.

Currently my phone of choice is my Treo, which has an option to disable phone portion for use, say in an airplane.
Now during this upcoming trip I thought it would be a good idea to maybe...throw a couple movies and or shows onto my 2gig SD card and keep myself somewhat occupied during my many flights.

BUT I'm wondering what the reaction of flight staff and or the people around me will handle this, seeing as the device I will have in hand is obviously of the cellular nature....

I stumbled upon this article: http://www.news.com/8301-13579_3-9796512-37.html
"ATA Airlines detains passenger for using iPhone in 'airplane mode' "

I was just wondering if anyone has experience using their smart phone (iphone, treo, etc) while in flight, and if you ever got any negative reactions from either someone next to you and or yelled at by a FA.
