Mark Gurman, writing for 9 to 5 Mac:
Now, we are hearing that Apple appears to be going all in on the special edition factor: sources say that Apple has decided to drop the “5” from the device’s name and simply call it the “iPhone SE.” This will mark the first iPhone upgrade without a number in its name and would logically remove it from a yearly update cycle.
In other rumored name changes to rumored devices news, the iPad Air 3 will likely be called “iPad Pro.” I’m not in love with the iPhone SE name, but I do like that this might foreshadow Apple removing numbers from the mainstream iPhone lineup in the future.
