I'm reconsidering the idea of buying an iPad Air 2013. Lack of budget is the main cause why I’m not looking better models. I read about Apple support cancelation (there’s not gonna be iOS13; iPadOS13 will be actual in September). So the last version of iOS is 12.4. For how long this device will still be usable? Jailbreak, would it help? Finally, I would appreciate some reviews of iOS 12 experience. Cheers!
