An iPhone with a 4-inch display and some features found in Apple's latest models will launch in March or April, according to a rumor that surfaced last week. The model reportedly will be called the "iPhone 5se" -- for "special edition" -- and will be offered at the same price point as the iPhone 5s. The iPhone 5se will have design features similar to the 5s, which was released in 2013, but it will have internal, hardware and software features gleaned from more recent models, according to the report, which cites unnamed Apple sources.
