Before it was the iPhone SE, it was the 5SE. Before that, the 6C. As listed on the leaked image, it seems that its current moniker might be the one that actually sticks.
Lastly, let's talk storage capacity. It looks like we're stuck with 16GB on the low-end, with a 64GB model available, too.
Disappointing as this may be, it's hard to be surprised by this move. But, with rumors that the SE will occupy a position in the Cupertino company's lineup of phones similar to the iPhone 5C in terms of pricing, and it seems likely that Apple will be saving the larger capacities for the iPhone 7.
