AT&T glitch causing upload issues on iPhone 4


If you're an iPhone 4 user having trouble sending pictures or other media, blame a network glitch from AT&T. The company says software issues in Alcatel-Lucent network equipment are hampering upload speeds for the iPhone 4, the Associated Press reports. The problems have been discovered only in some areas of the U.S., and AT&T is working to remedy the situation, says the AP. The upload woes represent the latest problem facing Apple's highly-anticipated smartphone since launching two weeks ago. Users had reported poor reception, blamed on the device's antenna. Apple responded by claiming an incorrect formula for determining signal strength was the reason behind the weaker reception. Also, as Cnet reports, the reception troubles have spawned a series of lawsuits.

AT&T blames slow iPhone 4 uploads on Alcatel-Lucent


AT&T is blaming the iPhone 4's sluggish upload speeds in some areas of the country on 3G wireless gear from supplier Alcatel-Lucent. On Wednesday, AT&T issued a statement saying a software glitch in the Alcatel-Lucent equipment is limiting data upload speeds from smartphones and data sticks using the latest version of 3G technology known as HSUPA. HSUPA is an acronym for High Speed Upload Packet Access. It increases upload speeds to between 500 kilobits per second and 1.2 megabits per second. "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," said Jenny Bridges, a spokeswoman for the company. Since the iPhone 4 is currently the only smartphone that AT&T offers that is using HSUPA, AT&T said that the problem only affects a small number of its wireless customers, which includes some laptop data stick users, who also use the HSUPA technology. AT&T said the company has come up with a temporary fix that should restore upload data speeds to regular 3G speeds.
