This morning Bloomberg is reporting that Sprint is all set to sell the iPhone 5 when it debuts in the next few weeks, and that they'll differentiate their offering with an unlimited data plan. Both AT&T and Verizon offerred unlimited data plans on the iPhone, but have since moved to tiered plans. New customers on both networks get a 2 GB limit on data each month, and pay overage fees for using more than that. This would give Sprint, the #3 wireless carrier in the US, an interesting advantage over its larger competitors. Offering the iPhone 5 with their popular unlimited voice and data plan, which costs less than the tiered plans offered elsewhere, could see the company gain quite a few customers who'd rather not worry about their data usage costing them extra money.
