Apple has received a record four million pre-orders for its new iPhones in 24 hours.

The number exceeds the pre-order supply, meaning many people will have to wait until October for their new handset to arrive, the company says.

Instore sales of the iPhone 6 and the iPhone 6 Plus open on Friday morning around the globe. 

Time zone differences mean Australian stores will be among the first in the world to open their doors on the day.

“iPhone 6 and iPhone 6 Plus are better in every way, and we are thrilled customers love them as much as we do,” said Tim Cook, Apple’s CEO.

“Pre-orders for iPhone 6 and iPhone 6 Plus set a new record for Apple, and we can’t wait to get our best iPhones yet into the hands of customers starting this Friday.”
