Apple introduced a new iPhone on Tuesday, dubbed the iPhone 8. It comes in two different form factors — the standard 4.7-inch model, and a larger 5.5-inch “Plus” model.

Here’s what you need to know up front: the iPhone 8 and iPhone 8 Plus launch on September 22, and they start at $US700. You can pre-order the phone starting this Friday, September 15.

As you might have already guessed, the smaller iPhone 8 is what starts at $US700; the iPhone 8 Plus starts at $US100 more, for $US800. Both models come with 64 GB of storage space, though you can opt for a 256 GB model that will cost a bit more.

Though visually similar to the iPhone 7, the iPhone 8 features a glass front and back — Apple says the glass back isn’t just a visual change, but a means of enabling the iPhone 8 and 8 Plus to add wireless charging functionality. You can place your phone on a charging mat — at least one that uses the Qi wireless charging standard — and it will automatically start charging without any wires.

Here’s a look at all the tech changes coming to the iPhone 8, care of Apple:

The iPhone 8 and 8 Plus are the newest versions of Apple’s 10-year-old iPhone product line, and they’re considered the base model. A third version of the newest iPhone, dubbed “iPhone X,” was also announced on Tuesday — it’s a more expensive, slightly different form-factor version of the iPhone.
