Bloomberg:

Sprint, the third-largest U.S. wireless carrier, plans to begin selling the device in mid-October under a deal with Apple for the next model, the iPhone 5, said the people, who wouldn’t be identified because the plans aren’t public. Becoming the country’s only operator to offer the device with unlimited data service for a flat fee may help Sprint draw customers from AT&T and Verizon Wireless, which already carry the phone, they said.
