do-not-track possibly solves the issue

I've had the "do not track" setting active on my iPhone since it was introduced. Three different UIDH sites show no evidence of the header when my phone accesses them via the Verizon data network, so perhaps Verizon observes this header and suppresses their perma-cookie header. Either that or the UIDH header is not injected for 3G-only phones, which is what I have.
