AT&T's 4G LTE network is live in San Francisco

New York City by the end of 2011? How's about San Francisco by the end of December 8th? We can't say for certain that it's lit up for good ("testing," you know), but at least for now it's absolutely screaming on our LTE-equipped AT&T handsets in downtown SF. Seeing similar? Let us know how it's going for you in comments below, and feel free to stick your tongue out in the general direction of the Big Apple. (They won't see you.) Video after the break.
