iPhone with AT&T cellular service can use AT&T wifi for free by request a link in text message. can anyone tell me how to use macbook laptop access internet at AT&T wifi location? I have iPhone with AT&T service. I tried to type that link in text message on macbook safari letter by letter, it did not work. I also change safari user-agent to "iphone mobile safari" and tried to access "attwifi" but i get different screen, it ask for user name and password not just the phone number it ask on iphone. Any suggestion will be appreciated, Thanks in advance.
