Apple is set to hold a special event on September 12 at 6pm GMT (10am PDT).

We'd love to suggest there's some cloud of mystery hanging over it, but we all know that this is where Apple unveils its latest smartphone.

As ever, we have a very good idea what to expect, courtesy of a whole bunch of leaks and credible rumours.

So, what exactly does Apple have in store for us this Wednesday evening?
