AT&T: Upload speed loss due to software defect

AT&T has released an official statement on recent reports of slow upload speeds observed by some iPhone 4 users. “AT&T and Alcatel-Lucent jointly identified a software defect—triggered under certain conditions – that impacted uplink performance for Laptop Connect and smartphone customers using 3G HSUPA-capable wireless devices in markets with Alcatel-Lucent equipment. This impacts less than two percent of our wireless customer base,” AT&T said in the statement. “While Alcatel-Lucent develops the appropriate software fix, we are providing normal 3G uplink speeds and consistent performance for affected customers with HSUPA-capable devices.”
