AT&T Begins Fix for Glitch That Slowed Some IPhones

AT&T said it began a fix for a glitch in software supplied by Alcatel-Lucent SA that was causing slower speeds in some areas of the U.S. for customers using Apple Inc.'s iPhone 4 and other devices.

Mark Siegel, an AT&T spokesman, said in an e-mail the Dallas-based carrier expected the issue to be resolved within two to three weeks. AT&T said earlier this month that fewer than 2 percent of its wireless customers were affected. Customers were experiencing slow responses when sending data such as photos or e-mail from their devices, Alcatel-Lucent said earlier this month.
