iPhone users across the U.S. were complaining Monday that AT&T Inc.'s wireless data network was down.
The network was down primarily in the West and Midwest, but by 7 p.m. on the East Coast, service was restored, according to Warner May, an AT&T spokesman. He said he didn't know when the problems started.
AT&T had isolated the problem and was still working on it, he said.
Voice and text messaging services remained fully functional but EDGE (Enhanced Data Rates for GSM Evolution) and 3G services were down, he said. While BlackBerry users had full service, users of other phones in addition to the iPhone were also affected, he said.
"The iPhone was not the cause," he said.
Several different online forums are full of iPhone users complaining of having trouble using the EDGE network. Posters claiming to be from Dallas, Cincinnati, Tuscon, Oahu, Hawaii, Seattle and Portland were among the West coast users who say they couldn't connect to the network. Users in Pittsburgh and Indiana also said they couldn't use the EDGE network.
A thread on Macrumors also describes users across the country having trouble.
