Apple starts shipping out iPhone 6s, 6s Plus preorders for Sept. 25 arrival

Ahead of an official iPhone 6s and iPhone 6s Plus launch on Sept. 25, Apple and partner wireless carriers began informing preorder customers on Saturday that their devices are now in transit, scheduled to arrive on Friday.

A number of customers who preordered Apple's latest smartphone last week, including AppleInsider readers like Sydney, began to receive automated email notifications containing iPhone 6s and 6s Plus shipment tracking information. The correspondence sent from both Apple and participating launch-day carriers notes free overnight shipping, but a delivery date of Sept. 25, meaning logistics providers will likely collect stock in warehouses before executing synchronized deliveries on Sept. 25.

It is unclear how Apple is conducting fulfillment operations, however, as some orders placed just minutes after pre-sales went live last week are still being processed, while others placed hours later are already en route.

Currently, Apple's U.S. website reflects stable supply of most iPhone 6s configurations, save for a two to three week wait time for new rose gold versions. iPhone 6s Plus stock is more constrained, with all colors, capacities and carriers showing estimated availability in three to four weeks. Other launch countries are exhibiting similar preorder limitations, though China completely sold out of its launch supply within one day.

Aside from preorder customers, iPhone 6s and 6s Plus is scheduled to land at Apple's brick-and-mortar retail stores on Friday. Launch day crowds might be larger than usual this year, as Apple is offering a new iPhone Upgrade Program that for now is restricted to in-store sales. Those interested can reserve an iPhone 6s and 6s Plus through Apple's website, but have to visit an Apple Store for payment and eligibility processing.
