NEW YORK (TheStreet) - Apple (AAPL) iPhone 6 and 6 Plus pre-orders hit a record of more than 4 million units sold in the first 24 hours, the Cupertino, Calif.-based company said on Monday.

The latest versions of the iPhone were so popular that demand exceeds 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," the tech company said in a release.

Apple announced its latest iPhone versions on Sept. 9, with pre-orders available on Sept. 12. Full rollout of the smartphone in the U.S. and 9 other countries will be available starting September 19. The two new models are available in a 4.7-inch and 5.5-inch Retina HD displays.

The iPhone 6 16 GB is available for $199 with a two-year contract and $299 for a 64 GB version. Apple is also launched a 128 GB version for $399 with contract. The iPhone 6 Plus is priced at $299 for the 16 GB model, $399 for the 64 GB model and $499 for the 128 GB model with a two-year contract.

Brian White, Cantor Fitzgerald (Buy: $123 PT)

We believe Apple is in the midst of another "Super Cycle". Leading up to Apple's special event, there seemed to be a commonly held view amongst investors to take profits; however, we believe this is shortsighted and could prove costly. Similar to "super cycles" that began in 2001 (iPod), 2007 (iPhone) and 2010 (iPad), we believe Apple is in the midst of another "super cycle" that begins with the rapidly growing "phablet" market via the iPhone 6 Plus and extends into the wearable category in early 2015 with Apple Watch. Already, we believe there is an insatiable appetite for the iPhone 6 Plus as demonstrated by rapidly expanding pre-order shipment times and we believe Apple Watch will prove to be a home run with the fastest, new product, first-year unit sales volume in the company's history, giving Apple a foothold in what we believe will be a large, wearable tech market. As more "things" become computers, we believe Apple's expertise in designing software, hardware and services to work together will prove invaluable. We also doubt Apple is finished innovating in new product categories. For example, we still believe there is a more robust Apple TV on the horizon that can reinvent the industry.
