MacRumors
Guys, don't you see? We've seen all these "iPhone 7" photos with the bigger camera, no headphone jack, but not a single "iPhone 7 Plus" image.
First of all, I don't think they'll call it "iPhone 7", just "iPhone" and "iPhone Pro". Like they do with their Macs and iPads/iPods (RIP). No more numbers. We'll just denote models by year. "[2016] iPhone". And like MacOS, they'll start naming iOS after places in California.
...and since I'm on a roll, next year they'll call their 10th iPhone "The New iPhone/Pro"!
By the way, storage & pricing just like the iPads: 32GB for $649, and 128GB for $150 extra. The iPhone Pro will come with 128GB, matte black (only available on Pro), dual cameras, but most importantly... a whole new design that hasn't been leaked (because it's fully waterproof, get it?), so we actually have something to be surprised about in September. We'll be so caught off guard we instantly preorder it with our new Apple Watches, forgetting it starts at $899, plus the cost of a new case.
Oh, and speaking of cases. I have my two cents to speak about the loss of the headphone jack. People are upset about not being able to charge and listen to wired headphones at the same time. Apple now already sells a battery case. What's wrong with updating their case to include a headphone port and requisite DAC? So those who want to continue using their current headphones can do so, and charge their phones at the same time, for only $99 more!
As for the iPhone Pro, Apple won't make a battery/headphone case for the same reason they didn't for the iPhone 6 Plus. It already has a bigger battery as a selling point. But what if... Apple doesn't take away the headphone port from the larger phone?!?! It would explain the back and forth we've been hearing in the rumor mills. Again, we've seen evidence of the "iPhone 7" case with no headphone port, but it would be totally Apple to make it and the dual cameras part of the $250 "upgrade".
