iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
iPhone 5s Shipping Estimates Improve to 1 to 2 Weeks in All Countries
Shortly after the launch of the iPhone 5s, shipping estimates for all colors and capacities slipped to 7 to 10 days and fell to a vague "October" timeline. In the middle of the month, shipping estimates were updated to two to three weeks, where they have remained until today.
According to several different reports, Apple significantly ramped up its iPhone 5s production in the weeks following the phone's launch while simultaneously cutting down on iPhone 5c production. Supplies of the iPhone 5c have remained plentiful since the phone was launched and all models and capacities continue to ship within 24 hours.
Apple's improved shipping estimates come following second and third wave launches on October 25 and November 1 that brought the iPhone 5s and the iPhone 5c to an additional 50 countries. The iPhones are now available in more than 60 countries, bringing Apple closer to its stated goal of availability in 100 countries by the end of the year.
In store supplies of the iPhone 5s appear to be improving as well, with even the gold iPhone 5s seeing greater availability as a Personal Pickup option across the United States.
