Has anyone tried to use their iPad on an Amtrak Acela train with the Amtrak Connect WiFi service? What I have experienced is that you can connect to the service easily and for the most part stay connected for several hours. Many Apps either don't work or are blocked by the AmtrakConnect filters. Basically, anything that the service thinks might be streaming will be blocked. Obvious streams like the ABC player, YouTube, but also the App Store, USA Today and others. I did an experiment and accessed the AppStore from my PC then typed the URL exactly on my iPad and was blocked. Contacted Amtrak and suggested they upgrade settings to allow more functionality for iPad and iPhone users. Any other experience?
