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.

AT&T’s second quarter is a fairly pivotal one, as it was the first full quarter since the CDMA iPhone 4 was launched on Verizon — ending AT&T’s exclusivity in the U.S. However, MacRumors explains why it isn’t easy to compare the results of each carrier:

“It is difficult, however, to compare exact sales numbers between the carriers and to Apple’s total figures, in part because AT&T’s activation numbers have historically included both new purchases and reactivation of used handsets that have been resold or passed down to other customers.”

AT&T did report that subscriber turnover had slightly decreased since the CDMA iPhone was released during the first quarter, however, the carrier hasn’t suffered any significant loss to the Verizon iPhone.
