AT&T users in San Francisco are reporting that the 4G LTE switch may have been flipped on. As you can see in the image above, users are indeed receiving 4G speeds. While AT&T has yet to officially launch their network in the area, we have seen other cities briefly light up for testing.

The good news is that the official switch should be flipped soon and you will be enjoying speeds three times that of 3G.
