-- Ready, set ... go!
Customers who visited the online Apple Store Friday were met with a message: "We'll be back," the message reads. "We're busy updating the Apple Store for you and will be back soon."
Devices won't reach consumers until Sept. 19, according to Apple.
The iPhones are also packed with new features, including "reachability." With a double touch, the display can slide down so users can reach "anything" at the top of the phone, an ideal feature for multitasking.
Apple Pay, the company's digital wallet that is aiming to be a credit card killer, will also be supported on the new iPhones.
Apple uses a new chip called the Secure Element, which is embedded in the new devices. The chip stores users' encrypted payment information and allows them to pay for items with a simple swipe.
The iPhone 6 starts at $199 for a 16 GB configuration, $299 for 64 GB and $399 for a 128 GB configuration, with a two-year contract.
The iPhone 6 Plus starts at $299 (16 GB), $399 (64 GB) and $499 (128 GB). Both phones come in three colors: gold, silver and space gray.
