AT&T says a software defect in its network is limiting upload speeds on the latest iPhone model in some areas.
It's the latest glitch to hit the iPhone 4, which went on sale in the U.S. two weeks ago. Last week, Apple acknowledged that holding the phone in a certain way might reduce its wireless performance, and that all iPhones show the wrong signal strength in some situations.
Dallas-based AT&T said Wednesday that a software glitch in network equipment made by Alcatel-Lucent is to blame for limiting the upload speeds of the iPhone 4. AT&T says a fix is in the works.
