What does sprint mean for iPhones?

Well I was looking for good phones and it said something about sprint iPhone 5 r something but I don't know what that means so can someone please tell me.

Sprint is a carrier like ATT and Verizon. So a Sprint iPhone would be an iPhone with service from Sprint.

Your iPhone would be on the worst cell phone carrier ever.

Years ago I had sprint and had the worst service ever. The call would constantly drop and customer service was a joke. When my contract expired, I had a 15 minute conversation with the customer service on why I was dropping.
