Apple seems to have a stupidly high IOS version requirement on the app, so yeah you would need to use the browser. There is likely some jailbreak tweak to get the app working, but I no longer have a jailbroken IOS device.Is Safari the only way I can access it?

Correct me if I am wrong, but I am pretty Google is responsible for maintaining YouTube's compatibility.Apple seems to have a stupidly high IOS version requirement on the app, so yeah you would need to use the browser.

Jailbreaking your Apple device comes with risks, they are considerably buggy from my experience. I'd go with jailbreaking an Android.Correct me if I am wrong, but I am pretty Google is responsible for maintaining YouTube's compatibility.
That being said, you might be able to get something through jailbreaking but I don't have anything to test that on.
I had a Jailbroken IOS device for quite awhile. Never had much issue. In fact the most buggy thing at the time was IOS itself.Jailbreaking your Apple device comes with risks, they are considerably buggy from my experience. I'd go with jailbreaking an Android.
I doubt it'd work as I think the main method via jailbreaking is modifying the app store to allow you to download a compatible version with your iOS version and it's going to be too outdated to work anymore.Is Safari the only way I can access it?
