Now that AT&T has full control of wireless hotspots like Starbucks and Barnes and Nobles, it looks like they're doling out freebies to their favorite customers: iPhone users. Apparently, if you've got one of Apple's devices, you can hop on the WiFi networks for exactly zero dollars provided you enter your phone number at a login screen. Great for iPhone owners, but a raw deal for everyone else, right? Not so fast, apparently a dumb hack gets you the service on the house too -- just switch your browser's user agent to Mobile Safari, and presto! Free internet. We can't imagine this is a hole that won't get plugged real fast, so get it while the gettin's good.
