There's a 2 week return period, and I wanted to be sure I'd be fine switching to iOS before buying an expensive new device. Part of the reason I'm switching is the new Pro models are a lot closer to Android phones with features like always on display. Based on the rumors, I was pretty sure what to expect today, so I have just been onboarding myself with iOS yesterday and today and can return the phone by the time I should have the new one in hand.
