iOS 9.1 Update
If you want to try the iOS 9.1 update on your iPhone 4s right now you can. This is thanks to the iOS 9.1 beta that was released earlier this month.
The emojis are the most exciting features coming with the iOS 9.1 update though there are also new APIs for developers. We expect Apple to deliver at least one more beta update before the public release so we could see more features emerge in the near future.
Be careful though. Beta software is typically buggy and the iOS 9.1 isn't for everyone.
