For the last few days, numerous iPhone users in major AT&T network hubs have noticed apparent 3G upload throttling. AT&T has just released a statement concerning the problem: its a bug with the Alcatel-Lucent HSUPA hardware, and they are working on it.
“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. 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.
In other words, something went kablooey, and until Alcatel-Lucent gets around to fixing the problem, users with HSUPA-capable devices like the iPhone 4 will be limited to regular 3G UMTS upload speeds.
Wonder if you’re affected? If you’re in NYC, Central Jersey, Boston, Orlando, Seattle, South Jersey/Philly, Columbus, Cleveland, West Houston, Phoenix, Northern Colorado, St. Paul/Minnesota, Suffolk County/Long Island, Quad Cities, South Jersey, Denver, Detroit Metro, Cincinnati, Baltimore, Salt Lake City, Las Vegas, Kansas City, Fairfax and Minneapolis… well, could be.
