AT&T is offering iPhone owners free Wi-Fi at hotspots managed by the company, including those at megachain Starbucks. But all the system checks is the user-agent string supplied by the iPhone's Safari browser and a phone number from a working iPhone. So anyone with a laptop can simply change their browser's user-agent string, put in the phone number of a friend with an iPhone, et voila! Free Wi-Fi. Why you won't get? The phone number of the cute barista you've been flirting with in vain. (Via Slashdot, photo by Synthesis Studios)
