The biggest Apple keynote of 2017 is just a few short hours away. And according to the rumors, its going to be one of the most memorable tech events in years.

When Tim Cook and Co. take the stage at the Steve Jobs Theater on September 12, we expect them to unveil not one, not two, but three new iPhones. A bunch of other new hardware and software is also on the docket, making this an Apple keynote not to be missed.

Here’s everything Apple will likely reveal.

The long wait for Apple’s big iPhone 8 upgrade is nearly over.

Apple is set to unveil its new lineup of iPhones during an event at the Steve Jobs Theater in Cupertino on September 12. This year’s model has been hyped more than any in recent memory. Tons of new features are being packed into the 10th edition of the iPhone for what will likely be the most innovative smartphone Apple has released in years.

Here are all the details and new features we know are coming:

The title of world’s second-largest smartphone brand no longer belongs to Apple.

New research data from analytics firm Counterpoint shows that Chinese smartphone company Huawei consistently surpassed Apple in smartphone sales during June and July to take over the No. 2 spot. Samsung remains at the top of the heap.

If you’ve been keeping up with the iPhone 8 rumors, you’ll know exactly what to expect from Apple’s big refresh this fall. But for the vast majority of fans, the upgrade will come as a huge surprise.

One survey has found that for ordinary iPhone users, the urge to upgrade is no more significant than it has been for previous, more incremental releases.

Apple will launch just two new iPhones this fall as opposed to three, according to a new report.

Fans were expecting updates to the existing 4.7- and 5.5-inch models, plus a larger “iPhone Edition” with a different design, an OLED display, and additional features. But one supply chain source says “it’s not true.”

Thanks to recent leaks, we thought we had a good idea what the iPhone 8 might look like. But forget what you thought you knew about Apple’s next-generation smartphone.

This apparent dummy unit blows all our previous conceptions right out of the water and leaves us with a lot of unanswered questions.

Thanks to a bevy of leaks that flooded the internet this week, we know more about the iPhone 8 than ever before. Even if only half the rumors turn out to be true, this year’s iPhone is set to be the most innovative device Apple has made in years.

Here’s what we know so far.

A new photo of what is believed to be iPhone 8 schematics reveals a surprising new design direction.

Apple appears to have done away with the smooth curves we’ve come to expect from its smartphones in recent years, opting instead for sharper edges and flat sides. This image suggests the next iPhone will be much like the iPhone 5, only bigger.

Much bigger.

The iPhone 8 may take some design cues from the Apple Watch, if the latest rumor out of Asia turns out to be true.

Apple will supposedly use an improved version of the Apple Watch’s stainless steel as the frame for the new iPhone 8. Glass in the front and the back will sandwich the stainless steel plate on the iPhone 8 but, according to the report, it won’t have a curved screen.

Supposed iPhone 8 schematics have surfaced ahead of the handset’s official unveiling this fall, revealing significant changes to its physical design.

As previous reports have suggested, the Home button has been removed to make room for a larger display, and there’s no sign of a fingerprint scanner elsewhere.
