AT&T Accidentally Provides Free Wi-Fi To All
SecureThroughObscure writes tells us about a hack broken by MacOSRumors: you can get free Wi-Fi at Starbucks, Barnes & Noble, and other AT&T hotspots if you know how to set your browser's user agent string (trivial on Safari), and know a valid iPhone phone number. ZDNet blogger Nate McFeters gives some more details and links. This can't last.
A surefire way to ensure that this hack lasts as long as possible is to keep it super-secret and not let AT&T know they screwed up.
But I'm sure posting the story to slashdot is fine. Nobody reads this site, after all...
