AT&T Opens Wi-Fi To iPhone Users

AT&T, aka the artist formerly known as the death star, will announce today free access across AT&T’s National wi-fi network for iPhone users.
There are 20K AT&T wi-fi locations across the country including 8K at Starbucks and 10K at McDonalds. Taking into consideration that there is a Starbucks every other block in the big city and a McDonalds every other mile in the little city, chances of hopping on wi-fi are pretty good regardless of your location.
iPhone users will receive a text message with an access code after connecting to the wi-fi and entering their mobile number. Sounds easy enough.

I know today is unicorn day, but really AT&T, is this make believe or are you actually doing something practical witth yo bad self?
