Preorders for the new iPhones will begin in the US on Friday Sept. 15 at 12:01 a.m. PT. At that time, you will be able to place a preorder at apple.com or in the Apple Store app on iOS devices. Using Apple's preorder system, you can upgrade through your carrier. Choose your model, color and capacity.

Historically, Apple drops the price of the previous year's iPhone models to make way for the newer models.

Despite rumors that this year's high-end iPhone will be the most expensive iPhone to date, it's likely pricing for the iPhone 8 and 8 Plus will follow the same trend.

If that's the case, here's what you can expect to pay for the new iPhone 8 and iPhone 8 Plus:

iPhone 8

64GB: $699, £699 or AU$1,079

256GB: $849, £849 or AU$1,329

iPhone 8 Plus

64GB: $799, £799 or AU$1,229

256GB: $949, £949 or AU$1,479 

You will be able to use Apple's iPhone Upgrade Program for all the new iPhone models (this isn't available in Australia). Pricing for the iPhone 8 and iPhone 8 Plus per month goes as follows:

iPhone 8 64GB: $34.50 or £37.95

iPhone 8 256GB: $39.50 or £45.45

iPhone 8 Plus 64GB: $40.75 or £43.95

iPhone 8 Plus 256GB: $45.75 or £51.45

The new iPhone 8 and 8 Plus will ship Sept. 22, and iOS 11 will become available Sept. 19.
