The iPhone 4S saw 1 million preorders over its first 24 hours.
It's not a huge surprise that the preorders are so high; Apple's Web site, and the carrier stores began to push back their delivery estimates toward the end of the day. The iPhone 5 is benefiting from pent-up demand among consumers who had sought a new design, bigger display, and a 4G LTE connection.
Based on the pre-order figure, Canaccord Genuity technology analyst Michael Walkley raised his estimate to 9 million to 10 million iPhone 5 units sold by September 29, up from a prior forecast of 6 million units.
Early indications for iPhone 5 demand have been positive. AT&T earlier said that it, although it declined to provide specific figures. The company said only that the iPhone 5 performed better than any previous iPhone over the first day and the first weekend.
A Sprint representative told CNET that its preorder sales quickly met expectations.
Apple enthusiasts, meanwhile, have alreadyon Fifth Ave., some having arrived as early as Friday.
Apple said that demand exceeded the initial supply. While a majority of the orders are expected to be fulfilled on Sept. 21, many are scheduled to be delivered in October, the company said. Both Apple and the carriers have already pushed back the shipment dates by several weeks.
"iPhone 5 preorders have shattered the previous record held by iPhone 4S and the customer response to iPhone 5 has been phenomenal," Philip Schiller, Apple's head of marketing, said in a statement today.
Apple took some heat with the seemingly minor improvements to the iPhone 5, which retains a similar look despite a stretched-out design to accommodate the larger display. Samsung Electronics even took out an, although over the weekend.
The design change, as well as the faster 4G LTE connection, are seemingly enough to warrant even higher demand for the phone. Apple's products have long come out of the gate strong; the real test lies in how long the company can keep up its momentum.
