I’ve been working here at TechCrunch’s SOMA office all afternoon and evening, and I must say, they truly get the shittiest AT&T reception I’ve ever seen, even by San Francisco standards. Place is like a Faraday cage.
TechCrunch is at 410 Townsend which is right next to the spot at the San Francisco Caltrain station where all of the tracks merge. Any iPhone user who rides the train on a regular basis can attest to the fact that that exact location seems to be a huge AT&T dead zone.
I’ve only used AT&T’s “Mark the Spot” app to mark one spot.
