Traditionally Apple releases a new iPhone (or two) every year. The major updates to design and hardware are usually done in a two-year cycle, but in between Apple releases refreshed hardware and improvements. Some argue that perhaps the “S” series of iPhones are a better buy as they tend to be more “refined”. That being said if you like the idea of being able to own a new iPhone every year, Sprint has the answer for you. The carrier has recently announced an update to their “iPhone For Life” plan.
