FORTUNE -- In early October, two weeks after Apple (AAPL) released the iPhone 5S, the device was out of stock at 92% of the 60 U.S. stores surveyed by Piper Jaffray's Gene Munster.
Piper Jaffray has been checking the stores twice a week ever since, and on Monday Munster announced in a note to clients that by Dec. 4, Apple had supplies in every one of them -- just in time for the big holiday rush.
"We believe Apple has caught up to demand, which we had expected ahead of the core holiday period," Munster writes. "In reflecting on the supply for the 5S product launch overall, we believe that net-net Apple has done a better job in suppling stores with phones proportional to demand."
CORRECTION: An earlier version of this story had Piper Jaffray checking stores every two weeks. According to Munster, they actually checked stores twice a week. "Bi-weekly," according to my dictionary, can mean either.
After suffering severe product shortages -- and frustrating untold numbers of would-be buyers -- Apple by fits and starts seems to be getting its iPhone 3G supplies in order.
Thanks to a pair of free tools that have emerged to take advantage of Apple's raw data feed of store-by-store availability, we're getting a much better picture of the company's supply and distribution problems than is afforded by the availability widget on MOREPhilip Elmer-DeWitt - Jul 24, 2008 8:04 AM ET
