Various Apple suppliers have reportedly begun shipping components for the iPhone 14 series. The California-based giant is expected to hold an event in September, where it is reported to unveil four new models, along with other products.

A paywalled preview on DigiTimes was spotted by MacRumors, with the following information mentioned. To make sure it is prepped and ready for an upcoming event, Apple typically asks suppliers to have components ready a couple of months in advance so it is able to cope with demand if shipments pick up in frequency.
