Maybe I'm crazy but I remember being able To watch videos on my phone. This morning I was checking the status of the nfl lockout and the videos say unavailable for this device.
I am getting this same error also on espn.com (content unavailable/not authorized for this device). I made sure I had the latest version of Flash installed and I tried accessing the content both over wifi (Verizon Fios) and 3G. Same result (blocked) both times.
The ESPN Score Center app has been force closing on me every time I try to open it lately, so the only way I can access the video is through the video widget. And the video doesn't play for me, I just get a perpetual loading screen.
