I have Comcast too. One needs to download the ESPN smart phone app. What you do is download that app, then click bottom right tab to log in with your Comcast ID/password. Then you see menu of all ESPN3 games. That will allow a guy to watch all those ESPN3 games. Then there is a Comcast Xfinity App. I have it. It is good. But I have never gone there to check if a guy can watch CFB games on it. My guess is no, only pre-recorded TV series shows. But back to ESPN app, here's the thing. Normally games on ABC(like this game) are not on live- also on ESPN3 in real time. And so in theory, there should be no way to watch this game live. However, after the game is over, in some time, the ABC games get moved to ESPN3 to view(different network, but owned by same parent company). ESPN3 changed a year ago. It used to be all games where free there. Now, some hot games are locked. One needs to enter TV cable provider ID and Password. But after the games are over, I think they all get unlocked, if memory serves. That just helps for normal PC online viewing. But on your smartphone, I dont think you will be able to view this game live, but you could with the ESPN view this game hours after it was over. However there are a few options I have not tried for live games via my smartphone that MAY work:
I have not tried to view on smartphone, but online normal such as a PC one can view sometimes games at Justin TV(though most get knocked off air mid games- do to copy right issues-them getting caught). But maybe a guy can view Just tv on his smart phone. I DNK as I never tried. And "first row sports eu" always has all games on. Their popup spam browser spam windows are annoying, unless you learn the art of getting through them. But I do not know if a game can be viewed from that website on a smartphone. I think it would have a lot to do with a guys smartphone, what type of browser and capabilities/if Adobe Flash would work well, of such phone's browser. You could always go there anytime, now, like for tonight's Monday Night NFL football and test and try I guess... Hope all this helps...
