I just check iTunes. No app for BTN2Go.....yet.
the is also from the website btn2go.com trh..."How do I watch BTN2Go?
This fall, BTN2Go will be available on three platforms: the Internet; iPad and iPhone. On the internet, fans will go to www.BTN2Go.com, choose their provider, enter their login information and then have full access to BTN2Go’s services. On the iPad and iPhone, fans will launch the BTN2Go app (which will be free in Apple’s app store), choose their provider and enter their login information to have full access to BTN2Go. Specific launch dates for each platform will be forthcoming." So if it's not available now it will be soon.
