Apple's iPhone 12 was previously reported to launch in October due to supply chain delays. Now, the news has come up again by Broadcom. We're expecting Apple to release four iPhone 12 models this year with the 5.4-inch iPhone 12 being the smallest and the 6.7-inch iPhone 12 Pro Max being the largest. The iPhone normally launches in September but this time around, the company is experiencing a delay by a few weeks.

Today, Broadcom has confirmed that its increase of chip shipments will run into the final quarter of 2020 (via Reuters). Analysts believe that the chips belong to the iPhone 12 series. This suggests that Apple will be launching its highly-hyped iPhone models in October.
