Apple CEO Tim Cook expects the tech company's Oct. 25 earnings to reach supply-demand balance on the iPhone 7 by the end of the quarter. But the iPhone 7 Plus came up with a different story.

Apple's CEO made it known that he's doubtful in calling for the tech company to reach supply-demand balance for the iPhone 7 Plus by the end of the quarter, as demand looks extremely strong on both iPhone 7 and iPhone 7 Plus, particularly on the iPhone 7 Plus against the forecast of Apple going into the product launch, according to Nasdaq.

Anyway, the iPhone 7 Plus comes in five color variants, rose gold, gold, silver, black, and jet black. It turns out that iPhone 7 Plus in jet black is the most difficult to buy, with the black iPhone 7 Plus coming in a close second.

In spite of that, even though the iPhone 7 Plus in jet black is still very hard to purchase, which was launched more than a month ago, the supply of these smartphones appears to be boosting up.

iStockNow, a website that provides real-time iPhone 7 and 7 plus availability monitoring, pointed out that it was virtually impossible to locate a jet-black iPhone 7 Plus in stock at Apple stores across America.

On the other hand, it seems the Cupertino based tech company might be considering another color option for Apple fans, according to Mac Otakara, the tech giant might have plans to present to the public a jet white or a pure white version of the iPhone 7 and 7 Plus. But, no words were out yet from Apple regarding the jet white model.

Even though Macotakara was one of the first sources to predict the ditching of the iPhone's headphone jack, however, this information about the a pure white version of the iPhone 7 and 7 Plus may be unreliable.
