According to an internal AT&T memo obtained by the site AllThingsD, the iPhone 3GS broke a number of sales records on its debut. Some milestones the carrier said it achieved include best-ever sales day in the company's retail stores, most transactions processed via the operator's IT systems in a single day and the largest order day in the company's history on its website.
In addition, AT&T said that on this year's launch day, iPhone 3GS sales exceeded those of the 2008 iPhone launch day by noon CST and sustained the company's previous peak hour record, also set in 2008, for 11 straight hours.
AT&T has not yet released specific sales figures for the iPhone 3GS. However, Apple said that it sold more than one million iPhone 3GS devices during its first weekend of availability.
