Pre-orders for Apple Inc.’s latest handsets, the iPhone 6, and iPhone 6 Plus, started at 3am ET on Friday, September 12th. By the same time the following day, over four million iPhones had been sold. Apple announced the record breaking first day sales figures for its two new phone models, but didn’t specify how many units of each model were sold. Both versions of the iPhone 6 are significantly larger than the iPhone 5, which received two million orders within the first 24 hours of its pre-order launch in 2012.

Customers who woke up early and placed orders as soon as Apple began accepting them will receive their phones on Friday, September 19th. Pre-order sales greatly exceeded Apple’s supply, so some customers won’t have their orders fulfilled until sometime in October. Limited supplies of both models will be available on Friday at Apple Stores, AT&T, Sprint, T-Mobile, Verizon Wireless, and select Apple Authorized Resellers. If you intend to score an iPhone 6 on launch day, you might want to consider heading to REI and picking up a nice tent and sleeping bag, so you can set up camp in front of your retail store of choice tonight. Or search on Craigslist for “iPhone 6 line sitters” and hire someone to do it for you. The Apple product launch line sitting business is a burgeoning industry.

The iPhone 6 and the iPhone 6 Plus start at $199 and $299 respectively, with a two year phone carrier contract. If you aren’t eligible for an upgrade, the full retail price starts at $649, and goes all the way up to $949 for the 128GB iPhone 6 Plus. Think of it as an investment. You can always sell it on ebay, where bids on several iPhone 6 auctions are more than twice the retail cost, despite the fact that the phone isn’t even available yet. Big screen mobile phone aficionados who don’t have the patience to wait for the iPhone 6 Plus to be readily available will soon have an alternative in the Galaxy Note 4, which is expected to launch in October.
