Recent rumors point out that Apple will be hosting its iPhone 12 event on October 13th. If these rumors are anything to go about, we will see the standard 5.4-inch and 6.1-inch iPhone 12 models ship ahead of the 6.1-inch and 6.7-inch iPhone 12 Pro models. According to the latest, Jon Prosser is committing to the date of the event and allegedly provides more details on the iPhone 12's baseline storage options and shipment details.

Past rumors have pointed out that Apple will double the base storage of the entire iPhone 12 lineup. Now, Prosser is claiming that the initial shipment of the iPhone 12 units will be available to distributors on October 5, almost a week before the announcement. The lineup will include a 5.4-inch iPhone "mini" which is "definitely the final marketing name" according to the leaker. Apart from this, the lineup will also include a 6.1-inch iPhone 12. Prosser further claims that the iPhone 12 Pro and iPhone 12 Pro Max will be announced alongside the standard models but the units will ship later in November.
