Following the retail launch of the iPhone 5s and iPhone 5c in Apple Stores and retail partners around the world today, Apple has provided a statement to AllThingsD calling demand for the new iPhones “incredible”. Apple also noted that the iPhone 5s is only available in limited supplies and sold out in many stores, lining up with what we first reported yesterday:

“Demand for the new iPhones has been incredible and we are currently sold out or have limited supply of certain iPhone 5s models in some stores,”

Yesterday we reported that many stores were getting little to no gold and or silver/white units of the new iPhone 5s, and that most retail outlets would only have the Space Grey model available for sale. We’ve heard that is indeed the case today even at Apple’s own retail stores as most locations have an extremely limited number of gold iPhone 5s units.

This morning the Wall Street Journal reported that Apple has instructed suppliers to increase production of the gold iPhone 5s by one-third, as shipping times for the device online have now been pushed back to October in most countries. That’s compared to the 7-10 days quoted for other colors of the iPhone 5s in most of Apple’s initial launch countries.
