I just finished using the Xfinity wifi network for three hours while away from my home. I believe it is a joint effort between comcast, optimum and time warner to provide free wifi within the NY metro area. It worked very well and all I needed to do was after two hours enter my log in info again. This may be the future. Since most of the time Ill be in the area Im thinking of canceling my 3 g order. Makes sense right?
