Sprint will indeed offer unlimited data for iPhone users
Phone Scoop was able to confirm that Sprint, as rumored, will be offering iPhone customers unlimited data plans starting at $69.99.
Sprint today confirmed to Phone Scoop via telephone that the Apple iPhone 4S will have access to all the same voice and data plans (at the same rates) that Sprint's current smartphones do -- including unlimited 3G data and the 5GB mobile hotspot cap.
Both AT&T and Verizon have switched to tiered pricing and no longer offer unlimited data plans for new customers (unless you've been grandfathered in, you're out of luck). With Sprint taking on a $20 billion gamble with the iPhone, something like this to help differentiate themselves from the competition could really go a long way in securing new subscribers.
