"There's not been a product announcement. There hasn't been any pricing decisions made. That's yet to come," CFO Rick Lindner told the Reuters Global Technology, Media and Telecoms Summit in New York.
AT&T, the exclusive U.S. carrier of the iPhone, has said it expects a next-generation iPhone that runs on faster, 3G networks, in the coming months.
Lindner said AT&T, the No. 1 U.S. telecommunications company, has more than 2.5 million iPhone customers, with the average subscriber spending nearly $100 a month on services after shelling out as much as $500 for the phone itself.
