“From the initial product launch until the end of 2012, AT&T has activated 72 million iPhones,” Horace Dediu reports for Asymco.

“Verizon began selling iPhones four years after AT&T and managed to activate 26 million since,” Dediu reports. “Sprint began nine months after Verizon and has activated 8.5 million.”

Dediu estimates “in 2013 T-Mobile USA will sell about 10% of its subs base an iPhone. That would make its contribution to iPhone sales about 3.4 million. It would also imply US sales among the top operators of 53 million iPhones in 2013.”
