Of course, the 16/32 GB versions are available in the largest quantities, the 64 GB versions being somewhat harder to find, but this is perfectly normal. Basically, Apple will guide buyers towards black terminals with gray cases, probably because they are much easier to manufacture, the other versions of the iPhone 5S will be available in sufficient quantities in the following months, probably around the winter holidays.

Because supplies are expected to be constrained, Apple is said to be preparing an update to its Apple Store app for the iPhone and iPod touch that can allow customers to monitor if certain new iPhone models are available at their local Apple Store.

"We will have grotesquely unavailable inventory," was how one carrier source put it.
