Engadget Mobile is reporting some major AT&T data outages on the east coast, from New York City to St. Louis. AT&T is aware of the reports and working on it, though as the big E notes a perusal of the AT&T forums shows a lot of unhappy 3G and EDGE users.
I'm doing fine down here in my little neck of the woods, where the recent 3G upgrade gets utilized by just a relatively small number of people. How about you big city folk -- emails coming in? Browser working?
