Market expectations are diverging again over whether Apple will apply an all-glass design to its 20th anniversary iPhone expected next year. A Jefferies analyst was reported as saying Apple has dropped the idea, while Bloomberg reporter Mark Gurman rejected that. The debate ties to former Apple design chief Jony Ive’s long-held vision of an iPhone that is essentially a single sheet of glass, and to questions over timing, naming and how far Apple moves toward that goal.

A next-generation iPhone Apple is preparing to mark the 20th anniversary of the iPhone may not directly replace the existing Pro model, a report said. With major design changes expected, observers point to Apple increasingly separating the roles of the Pro and Air in its lineup. A report said the anniversary model could sit closer to the Air family, potentially creating a separate top-end tier alongside Pro models.
