According to Bloomberg, Sprint will not only sell the iPhone 5, they'll have an unlimited data plan to go with it. If true, it will be huge for Sprint because neither AT&T nor Verizon offer unlimited data anymore.
From the Bloomberg story:
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.
AT&T and Verizon both moved to tiered data plans earlier this year, in an attempt to free up bandwidth across their network and improve overall performance. Meanwhile, Sprint is a third-place mobile provider trying to catch up to the competition. If there was ever a move, this is it. [Bloomberg]
