iPhone 6 pre-orders break Apple record. Now come delays.

The iPhone 6 and iPhone 6 Plus became available for pre-order early Friday morning. But many sites, including the Apple Store, were not ready for the purchasing bonanza. 

Apple reports that it received four million first-day pre-orders of its new iPhone 6 and iPhone 6 Plus – a record for the company. Now many customers will have to wait until October for their new phones.

Apple opened up pre-orders for its iPhone 6 and iPhone 6 Plus Friday. But customers eager to purchase Apple's next-generation smart phones found they were unable to access websites for the Apple Store and for wireless carriers such as AT&T, Sprint, Verizon, and T-Mobile.

Supplies of the iPhones have reportedly been running low, particularly those being sold by wireless carriers, as they do not receive as many iPhone models as does Apple, reports 9to5Mac. 

As of 9:45 a.m. Friday, Mashable reported that models of the 5.5-inch "phablet" iPhone 6 Plus are now sold out in the US and will not begin shipping for up four weeks.

This botched pre-order follows Apple's splotchy live-stream of its keynote event earlier this week where the iPhones and the new Apple Watch were unveiled. The live stream repeatedly stopped working and many users heard a dubbed voice-over of Mandarin playing in the background during the keynote. 

Upon learning of Apple's glitches early Friday morning, users vented their frustrations on Twitter. 

The Apple Store came back online at 6:07 a.m. 

The iPhone 6 begins selling at $199 while the iPhone 6 Plus begins selling at $299.
