The analyst firm has heard that the 4.7-inch iPhone will be called the iPhone 6 Air (a name previously reported to belong to the bigger model), and the 5.5-inch model will allegedly be named the “iPhone 6 Pro”
The more I think about it, the more I think it only makes sense. A rebranding of the iPhone will enforce the idea that the iPhone 6 is much more than an incremental revision of the iPhone 5. This will be a complete different beast requiring its own naming rules. So, there you have it: 4.7” will get the Air monicker while the 5.5” device would get the Pro monicker. I’m not very enthousiast regarding the latter. Also, iPhone Air and iPhone Pro could be simpler instead of adding the middle “6”.
