In its second quarter financial results today, AT&T revealed it had activated 3.6 million iPhones during the three-month period ending in June. This figure is identical to that announced for AT&T's first financial quarter, however, it is an increase over the 3.2 million devices activated during the same quarter last year.
After falling over the last 12-18 months, the number of new customers activating iPhones seems to have stabilized. 24% of iPhone activations were for new customers, which is just slightly higher than the first quarter, and significantly lower than the 40% rate during the early days of the iPhone.
