Defying Apple’s own expectations, the gold-colored iPhone 5s may be the most popular version of the flagship handset at launch. The Wall Street Journal reports that Apple has increased production orders on the model by one-third following high demand. The gold iPhone was apparently the first to sell out, following early reports that Apple had a very limited supply of the iPhone 5s.

9to5Mac reported last night that while customers should be able to order any version of the iPhone 5s online, only the Space Grey (black) version will be available from many physical retailers at launch. Based on previous launches, Apple apparently expected the black model to be a big hit, but it looks like many consumers were hoping to pick up the gold iPhone 5s, as it is the only one that can’t be mistaken for an iPhone 5 thanks to its unique color.

The iPhone 5s comes equipped with a 64-bit A7 processor, the M7 motion coprocessor, a 4-inch Retina Display with a resolution of 1136 x 640 pixels at 326ppi, an 8-megapixel rear camera, a 1.2-megapixel secondary camera, and a 10-hour battery. It comes running iOS 7 out of the box and is the only iPhone with a fingerprint sensor built into the Home Button.
