An AT&T Wireless data outage this morning throughout the eastern U.S. may have been caused by, well, excessive iPhone usage...

"AT&T and iPhone users all along the East Coast - including Connecticut, Massachusetts, Maryland, Missouri, New Jersey, New York, Pennsylvania, Rhode Island, Washington, D.C., and Virginia - are reporting that Web, e-mail, and all other data access is dead, even though their phones are showing '3G' and 'EDGE' icons and full service bars," writes Yahoo's Ben Patterson.

"An AT&T spokesman acknowledged that the network experienced a routing problem that had been corrected about noon EDT," writes Computerworld's Matt Hamblen.

And on the same theme, according to The Dallas Morning News' Andrew Smith, "An 18-page complaint filed in San Diego says that AT&T and Apple have knowingly sold enough iPhones to repeatedly overwhelm AT&T's 3G network. By doing this, the suit argues, the two companies have broken their promise to provide 3G data service inside certain areas to iPhone users."
