Additionally, Apple is said to be working on a less expensive iPhone that could launch in the second half of the year. The device is said to have a 4-inch display but a different casing than the higher end phone. Although Apple has looked at different color shells, its release plans are still unknown.
How the innards of the next iPhone may differ from the iPhone 5, which went on sale last September, remains unclear. Apple often upgrades the processor and other components like the camera between models. Apple is also expected to ship the next version of its iOS mobile operating system around midyear, other people familiar with the matter have said.
