Well here's a turn up for the books, Apple's new iPhone 6 and iPhone 6 Plus are proving rather popular with eager fans pre-ordering the firm's new, larger smartphones in their millions.

Apple has confirmed that it took a record 4 million pre-orders for the new iPhone 6 and iPhone 6 Plus on the opening day of pre-orders (Friday 12 September).

The iPhone 6 and iPhone 6 Plus officially go on sale in 10 countries, including the US, UK, and Australia on Friday 19 September, with 20 more countries getting an iPhone treat from September 26 - but Apple is already warning of stock issues.

Supply warning

On its site, Apple writes "Demand for the new iPhones exceeds the initial pre-order supply and while a significant amount will be delivered to customers beginning on Friday and throughout September, many iPhone pre-orders are scheduled to be delivered in October."

That's going to come as a bit of a blow to hungry fans desperate to get their hands on the latest iPhone handsets, but there is a small crumb of comfort.

"Additional supply of iPhone 6 and iPhone 6 Plus will be available to walk-in customers on Friday, September 19 at 8:00 a.m. local time at Apple retail stores."

Of course that means waiting in line for probably hours, potentially days, so it's time you took a long, hard look at yourself in the mirror and asked yourself; "do I really want the new iPhone that much?"

If your answer is yes, well we wish you the best of luck. *salutes*
