Apple have really turned the “let’s screw over our customers” dial up to 11 this year.
The normal iPhone will be limited to 2.0 USB speeds whereas the Pro will have access to 3.0 USB speeds. There’s literally no reason to limit the normal iPhone to 2.0 speeds except to be dicks. I fully expect the likes of Lewis Rossman to announce that it’s just a software setting that can be changed if you jailbreak your iPhone
