Hey FunkyBoss -
I just paid the 5 bucks for NFL mobile streaming on an original verizon motorola droid razr on Sunday - I have been using my razr for streaming (youtube, hulu, netflix) to my tv for years using the HDMI out (still have the grandfathered unlimited data plan) - I have always been disappointed that the NFL app didn't stream as it would detect the HDMI and shut down.
I noticed they recently updated the app so I thought I'd give it a shot again and low and behold it streamed to the TV no problem (this was Sunday, Sept 8). The quality is not HD but definitely good enough (this was over 4g network) - I don't have cable or internet so this was a sweet solution for $5/month (nfl network - Thurs night games, redzone on sunday, and monday night games on espn). Since Sunday I noticed they have updated the app again - I'm a little nervous to update incase this phone-to-TV streaming was not intended...if anyone tries the newest version and it still works let me know and I'll update - (my version is 8.2.1)
