Today Apple will soon start rolling out the big iOS 9 update so get ready for it. It’s a good idea to first update all of your apps as many will be adding support for iOS 9.
Make sure you have a fast network connection, espeicailly if you have more than one device that will get the update. These tend to be big so go as fast as you can. I’m going to wait to update my two iPads, iPhone 6 Plus, and Apple Watch until I get to the coworking space with its insanely fast fibre connection.
I’ve been running the iOS 9.1 Public Beta on the two iPads and it is a sweet update. I’ve had no issues so you should be able to safely update your devices.
