I have AT&T Uverse Mobile on my iPad 2 and my iPhone 4. The apps on both devices seem to work. Howeve, when I go to the guide, my local channels are missing. I see displayed all other channels (ie. sports, news, movies, etc.). Channels 1-99, local channels, only display four channels whch don't appear on my line up. On my Uverse boxes in the house, all channels are displayed. How can I view these. Channels?
