The iPhone 5S is now fully stocked at Apple Stores, Piper Jaffray analyst Gene Munster says, according to CNET.

In his latest survey of 60 U.S. Apple retail stores, conducted on Dec 4, Munster found that 100 percent of iPhone 5S models were in stock at each store. That number was up from 24 percent two weeks ago and 8 percent at the start of October.

"We believe Apple has caught up to demand, which we had expected ahead of the core holiday period," the analyst said in an investors note released Monday, Dec 9. "In reflecting on the supply for the 5S product launch overall, we believe that net-net Apple has done a better job in supplying stores with phones proportional to demand."

Last week, Apple lowered the estimated wait time for online purchases of the 5S to 1 to 3 business days. Previously, it had been 3 to 5 days.
