Sprint will offer the iPhone 5 in mid-October and will bundle it with an unlimited data plan, Bloomberg reported on Friday. The carrier hopes its unlimited data plan offering will attract customers away from AT&T and Verizon Wireless, which both cap iPhone data packages. Sprint currently offers all-you-can eat data and voice plans and its Everything Data plan starts out at $69.99 per month with 450 peak minutes. “The advantage of unlimited is, it’s cheaper for the big users,” Bank of Montreal analyst Peter Rhamey explained to Bloomberg, noting that unlimited plans are attractive because “people don’t like bill shock.” Bloomberg’s report is on a par with a recent Wall Street Journal article that also suggested Sprint will begin selling the iPhone 5 in October. In addition, BGR exclusively reported that Best Buy is anticipating selling a Sprint-branded iPhone 5 and that pre-orders should begin soon.
