Apple on Monday announced they'd set a new record for iPhone pre-orders with over four million secured in the first 24 hours. Demand exceeded the company's initial pre-order supply although there are still a few ways to get your hands on a new iPhone later this week.

In a press release, Apple said an additional supply of iPhone 6 and iPhone 6 Plus will be available to walk-in customers on Friday at 8:00 am local time at Apple retail stores. Customers are encouraged to arrive early or order online for store pick-up.

Both models will also be available this Friday from AT&T, Sprint, T-Mobile, Verizon and additional carriers as well as at select Apple Authorized Resellers.

Apple didn't detail how many of each handset they sold but based on what we've been hearing around the web as well as shipping estimates, the iPhone 6 Plus sold out first. It's unclear whether this can be attributed to higher demand for the larger-screen device or a supply shortage.

The four million mark is twice what Apple achieved back in 2012 with the iPhone 5 during the same 24-hour period. The company didn't announce pre-order figures for the 5s / 5c last year although they did manage to sell nine million combined handsets on opening weekend. Given the pre-order figures this time around, it's looking like Apple could eclipse that figure once again - so long as there's enough inventory to go around.
