AT&T Begins Fix for Glitch That Slowed Some IPhones

July 26 (Bloomberg) -- AT&T Inc. 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.

Siegel declined to comment on how much the project will cost. Two percent of AT&T’s 90.1 million wireless subscribers works out to 1.8 million people.

AT&T added 42 cents, or 1.6 percent, to $25.96 at 4:01 p.m. in New York Stock Exchange composite trading, for the highest closing price since May 3. The shares have lost 7.4 percent this year.
