AT&T is planning some fixes for a problem with slow upload speeds on the iPhone 4.
When the device launched we saw awesome speed that surpassed our EVO 4G. Then it suddenly went to cr*p. There was speculation that AT&T was capping the speed at which the device could upload.
AT&T blamed a "software defect." In their official statement made in early July, they said:
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.
Several weeks have passed, and AT&T now has a patch to resolve the issue.
The upload issue seems equipment-related as it is said to only affect users in areas that use Alcatel Lucent gear.
The patch will be gradually "on a phased basic over the next two to three weeks," according to Mark Siegel, spokesperson for AT&T who spoke with Reuters regarding the issue.
