At 12:01 a.m. (PST), September 12th, AT&T, Sprint, Verizon and the Apple online store will all make online pre-order options available for the iPhone 6 and iPhone 6 Plus.

Pre-order supplies on iPhones have historically sold out within minutes of their availability. For this reason, it is important for anyone interested in pre-ordering to first check with their mobile carriers in order to be certain that they are eligible for a phone upgrade.

The iPhone 6 and iPhone 6 Plus will be available at retail stores such as Apple, Best Buy, Radio Shack, Walmart and Target beginning September 19th.

Apple’s iPhone 6 and iPhone 6 Plus will be available in 16, 64 and 128 GB versions, priced at $199, $299 and $399, respectively, for the iPhone 6, and $299, $399 and $499, respectively, for the iPhone 6 Plus.

Apple officially announced the release of the iPhone 6 and iPhone 6 Plus this Tuesday at a special media event in California. The new phones incorporate one of the most significant changes in the history of the iPhone: the move to larger displays.

A full rundown of the iPhone 6 and iPhone 6 Plus’s new features can be found on the official Apple website.

All new iPhones will ship with iOS 8, Apple’s latest mobile OS.
