This day has been a long time coming, but it is apparently finally here. The BTN2Go app, the mobile streaming app created by the Big Ten Network, now includes live video support for Comcast XFINITY subscribers. This inclusion should be platform wide, meaning the Comcast XFINITY login should be available on Android and iOS devices.
For some users of the app, including myself, the Comcast login may be difficult to find, as it is located at the bottom of the alphabetical list (maybe for XFINITY?). The logo for the service also, rather than being either the Comcast or XFINITY logo, actually reads "Beta," so this is likely an inclusion in its infancy.
Streaming seems to operate fine on my DROID DNA on Verizon, and I know I'll be using this thing like crazy at tailgates during football season and in the office for basketball.
For those frustrated users who deleted the BTN2Go app in the past, here's a link to the Android version in the Google Play Store. Enjoy!
