I assume there are similar opt-outs for AT&T, Sprint, T-Moblie, etc. Anyone maintain a page of links for how to access the opt-outs?

Interesting, I just tested my device over AT&T LTE, but there was no UIDH header.

Edit: There is an x-acr header, which contains a curiously large amount of encoded data, far too much to be any reasonably sized id. Anyone know what it is?

I see this as well. AT&T LTE with iPhone 5 (running 8.1).

Well, I found the AT&T page. Wow, they make this very difficult to opt-out. http://www.att.com/gen/privacy-policy?pid=24339

This is bullshit. You shouldn't have to "opt out" of tracking in the first fucking place.
