iOS 17 now & update in the future
What's an inexpensive iPhone that uses iOS 17 and can probably upgrade to future iOS? I ask because the iPhone 7-Plus that I use is stuck on iOS 15 and my main app, Outlook for iOS app, that I want to use is not supported by 15 so I'd like to upgrade as cheap as possible since I don't have any spare money these days.
I'd even be totally willing to buy a used iPhone off of one of the users here who has upgraded to another model.
I realize I'll not be able to use my awesome OtterBox protector case on a different model. Maybe a used one would also come with a useable case.
I use T-Mobile service. I really don't care about how many gigabytes of storage it has or anything like that. A basic iPhone is all I need.
