Supply Of Apple Inc. iPhone 6 Improves, Still Remains Tight

He further explained Apple stores indicated that 56% of iPhone 6 and iPhone 6 Plus models were available as of Dec. 12. This was a huge increase from the month prior, but unfortunately it is still not at the 100% availability initially expected.
