Verizon Wireless and Sprint have yet to knock AT&T off of its throne as the most prominent iPhone carrier in the United States. According to new data from Localytics, 56% of iPhone 4S owners are on AT&T, 32% are Verizon Wireless subscribers and just 12% are on Sprint. “Looking at the iPhone 4 distribution as a comparison, Sprint seems to have eroded more of Verizon’s market share than AT&T’s — of the previous generation handset, 60% are on AT&T versus 40% on Verizon,” Localytics explained in its report. The firm noted that AT&T’s share is larger because it has an existing base of iPhone users. “Many longer-term AT&T users, especially those holding iPhone 3GS and earlier devices, are off-contract or nearing the end of their contract,” Localytics explained. “AT&T has been aggressively leveraging the iPhone 4S to sign these customers to new two-year contracts, and the data in this study suggests that tactic may be working.”
