Apple said it received a "record number" of first day pre- orders of iPhone 6 and iPhone 6 Plus, the biggest advancements in iPhone history with over four million in the first 24 hours.
"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," Apple said in a statement.
Last year, Apple sold nine million units of iPhone 5s and iPhone 5c models within three days after the launch of the new iPhones on September 20.
The iPhone 6 and iPhone 6 Plus will be available to customers in India from October 17, less than a month from its global launch.
