So the thing is..
If you are a t-mobile subscriber, you still get the wi-fi access because there is a partnership with those two so you people don't get screwed.
If you are a starbucks card holder (the VISA) you get free 2 hours of access everyday
If you are an AT&T broadband subscriber, you get it for free always
Everyone else has to pay, its 20 bucks a month.
