Filed under: Cellphones, Wireless Ruh-roh. AT&T's wireless data service seems to be down in a major way, at least on the eastern half of the country. We're seeing problems with both Edge and 3G from places such as Boston, New York and St. Louis. It's primarily iPhone users pinging us on this, and in AT&T's forums, but we're guessing it's not just limited to them. How is it looking for you?[Thanks to everyone who sent this in]
