iPhone 8 pre-orders are available now and going fast

Now that you've seen the iPhone 8 and 8 Plus and decided you've gotta have it — or are at least considering Apple's latest phones — it's time to make a pre-order, as Apple and carriers began taking orders for the device earlier today (Sept. 15). Demand for certain models has been so strong that those ordering the device now may notice a delayed shipping date for the model of their choice. It appears that the 64GB versions of the iPhone 8 and 8 Plus — specifically those in gold and space gray — are in the highest demand, as the ship dates for those devices read "1-2 weeks" instead of Sept. 22.

Apple, AT&T, Sprint, T-Mobile and Verizon take pre-orders via their websites, but the most convenient method is by using Apple's own Apple Store app for iOS. The app's Apple Pay integration is tighter than on most other devices, except for the Touch Bar MacBook Pros. Trying to make this payment on another machine and still use Apple Pay might leave you juggling your devices.
