> There is no iphone3 appstore where I can buy iphone3 apps
Of course there is. It's called the App Store, and it's where all of the apps that support the iPhone 3g are. And just like your example with the PS3 these apps are likely not maintained. The fact that you can't download the latest version and run it on an iPhone 3g is no different than not being able to play PS4 games on a PS3.
I have an iPhone 4 in my desk, as a reminder of how quickly the world moves. I just turned it on. It connected to wifi and worked just fine. I'm sure no different than your PS3.
Many apps you could get and run on iphone 4 like youtube no longer exists or no longer supports iphone 4. It isn't the same thing. If you could open up your iphone 4, go to the appstore and buy the same apps and run them just fine like you could 9 years ago then it would be the same thing.
I had a first generation iPad that I dug up last year. If the newest version isn’t available, you can still download the “last compatible version”. In some cases, the backend APIs that are needed to support the app have been deprecated.
