Launched in 2011 as the hardware vanguard for Siri, the iPhone 4s was a big software leap for Apple. But iOS 10, which even focused on making Siri better than ever before, will not work on the iPhone 4s. Sad!
Apple will actually be burying all iOS devices that are over four years old. The iPad 2, iPad 3, iPad mini, and all iPod touches (except the latest generation) aren’t supported in the iOS update.
