You probably haven’t received the alert yet, but the iOS 10 update is waiting for you in settings on your iPhone. Apple will probably announce it soon, but you can get a jump start on one of the most aggressive updates ever. The improvements are amazing.
Once you download the iOS, the lists of upgrades will appear on your iPhone. I quickly took a photo of them so I could share them with you. The iOS 10 update takes about 40 minutes to download, so leave yourself plenty of time.
Enjoy reading all the benefits.

I did it several days ago when I got the update alert. Personally am sorry I did it! It’s quite invasive and uses a tremendous amount of the battery even while not using it. The biggest annoyance for me is how it re-arranged my 50,000+ photos.
