AT&T has done away with a special code used to track individual users' internet activity on its phones after its discovery sparked anger.By Sebastian Martinez | November 16, 2014
Well, that didn't take long — AT&T has pulled a secret ID code it used to track people's internet activity on their phones less than a month after the code's existence came to light.
They're known as "supercookies," and they basically let the carriers see all of the places a user went online, and there wasn't really anything users could do to stop it. Verizon also uses them. (Video via AT&T)
TIM STEVENS VIA CBS: "Verizon does offer an opt out, but the problem is while it will opt you out of their advertisement program, it doesn't actually stop them from putting this ID onto your information which is a problem. AT&T's system says if you opt out they will stop putting that ID on there, but ultimately there's no easy way to flip that off. "
