AT&T today posted one of its best-ever spring quarter results credited mostly to the iPhone 3GS launch. The company says it added 1.2 million cellphone subscribers, an all-time high for spring. It adds that it activated 2.4 million iPhones between April and the end of June. The number ties that of the iPhone 3G launch quarter but is considered a record as the iPhone 3GS and $99 iPhone 3G were only available for less than two weeks in the period covered by the results.
The carrier adds that the June 19th iPhone 3GS release day was a record of its own in multiple ways. Both the company’s retail stores and its website saw their best single sales days ever, eclipsing previous iPhone launch days as well as usual holiday peaks.
And the iPhone keeps on truckin’.
