Apple announces 'special event' on September 7
This time around, a number of leaks are suggesting that the iPhone 7 will ditch the headphone jack, and possibly add a second camera to the back of the iPhone 7. A dual camera would allow the iPhone to take two photos at the same time with different settings, and then combine the two for the best version after the fact.
Omitting the headphone jack on the other hand seems to be rather controversial; the company will likely allow consumers to continue to use their existing headphones with an optional adapter.
In addition to the latest iPhone, Apple may also use the event to introduce a new version of its Apple Watch.
