Unfortunately, it looks like the method is still in effect. Philip Neustrom, the co-founder of Shotwell Labs, lately found two demo websites that would pass account details if you visited from a mobile connection. By simply inserting a zip code and clicking a button, the site would spit out the full name, current location, and more data. It would seem that these sites are grasping the information from the same means that Verizon got busted for. That presentation, the Unique Identifier Header, added data to HTTP requests from Verizon consumers and then, for a fee, would let websites see the info. AT&T has a comparable plan called the “Mobile Identity API”.
