What changes will we see with the iPhone 7?

Answer 1

So far there is a rumor that the phone is waterproof. We hear that there will be no standard headphone jack, and that there will be a dual camera, which will allow the phones to take photos that have added clarity, and also probably some other cool photo enhancements.

Some (possibly unreliable) sources say that the new phones will be available in blue. We also hear that the home button will be pressure sensitive rather than something that actually depresses. That's a change that some (along with the lack of a standard headphone jack) think indicates the waterproof rumor is true.

We also hear that Apple will no longer offer a 16 GB version, but that 32 GB will be the new standard (which likely also means a higher price). The iPhone 7+ might even have 256 GB of storage, which for a phone is huge.
