For those who use the Delta Airlines free in-flight wi-fi entertainment system to watch movies/shows/etc on their iPhones/iPads in-flight... The web site will claim you're using an unsupported internet browser if you're using one of the iOS betas and therefore won't let you get to the movie selection page. I tried Chrome and Safari and requested desktop site with no joy. I didn't have a browser installed to let me change the user-agent string, or I would have tired that.
Anyway, you might want to plan ahead if you were counting on using it.
