The next iPhone could be out by Sept. 9, and a lot of people are eager to find out what the next iPhone successor will have to offer.

However, there is a question on whether the next device will be readily available since it is a known fact that Apple's slew of devices fly off the shelf pretty fast.

But this piece of update from Apple analyst Ming-Chi Kuo could be a setback, especially if Apple doesn't have enough supply of the next iPhone, touted to be the iPhone 6S.

Although little has been known on what the next iPhone variant will carry, the fact remains that people will be interested in getting one once it does become official. For now, there are rumors that suggest that the next iPhone will have a Force Touch feature, as well as something that would run on an A9 processor.

Aside from that, it is believed that the iPhone 6S will likely look a lot like its previous models — the iPhone 6 and iPhone 6 Plus. It could be thicker, but such remains to be confirmed and seen.

There was no official reason given on why the production has been delayed by about one to two weeks.

According to a report from Apple Insider, 60% of the production of iPhone 6S could be shouldered by one of Apple's long-time partner Foxconn, with the rest handled by Pegatron. Full scale production is reportedly slated for later this month to serve as an advanced production for the expected Sept. 9 launch.

Concern now looms in the air for the people who are expected to want the iPhone 6S, considering how hard it is to get one once the device is officially launched. With the said delay, it is hoped that such would not radiate and become a problem which could eventually pile up, especially when demand for the upcoming Apple device grows large.
