4 You’ll Need iOS 11.2.5
Apple on Tuesday released iOS 11.2.5. It’s a fairly small update to the mobile operating system, but in its release notes, Apple says that the software update adds support for HomePod. Presumably, that means you’ll need iOS 11.2.5 to get the most out of HomePod, or even sync with HomePod at all.
With the addition of HomePod support, iOS 11.2.5 will let users seamlessly and automatically synchronize their Apple ID credentials, Siri, Apple Music, Wi-Fi login details and other important settings to the smart home speaker. Thankfully, iOS 11.2.5 is a free update (find it under Settings > General > Software Update).
