AT&T has confirmed that its east coast mobile data service is back up and running.
The network went down yesterday morning in Massachusetts, New York, Rhode Island, Pennsylvania, Maryland, Virginia, Illinois and Missouri. It has been back up and running since noon.
The outage has hit few BlackBerry users, but iPhone owners are particularly outraged.
"There are multiple reports of a widespread AT&T data outage affecting 3G and Edge networks," said one posting on the Apple support bulletin board.
"Phones show as connected to 3G or Edge, but cannot access data. Voice, visual voicemail and SMS are unaffected."
AT&T has not confirmed what caused the problems but they reportedly stemmed from a router issue that led to data traffic being misdirected.
