What versions can't access the App Store anymore? I've tried Catalina recently, and that still worked fine, but it only stopped getting security updates in 2022, so it's only been a few years.

Also, I've barely ever used the OSX/MacOS app store anyway, and from what little I've heard from other people, it's not really all that great nor popular a place to get your software from.

Cant you technically access the old jailbreak app stores on a 5? I would assume these phones were jailbroken far more commonly than modern iPhones. I feel like I dont hear about anyone jailbreaking them anymore.
