While Apple has explored such a device for years, the plan has been progressing and a less expensive version of the flagship device could launch as soon as later this year, one of the people said.

The cheaper phone could resemble the standard iPhone, with a different, less-expensive body, one of the people said. One possibility Apple has considered is lowering the cost of the device by using a different shell made of polycarbonate plastic. Many other parts could remain the same or be recycled from older iPhone models.
