Well. . . . . . . I still cant get Watch ESPN even at home. Do you have to re download the app and sign up via frontier?
Also the McAfee that used to come included with Uverse expires today. Frontier was kind enough to offer it to me for an additional $24.99 a month. They still suck. . . . . . . . alot.
Using the Watch ESPN app you should be able to find frontier as one of the options now and then sign in. Watch ESPN requires you to sign to Frontier regardless of the IP addrees I think.
