Post here and tell us how it went.
Are you having any issues?
Hi all…
I updated my iPad Air 128GB (first Air), 2 iPhone 6s (128GB & 64GB), and my old iPhone 5s 64GB -
which has now become my iPod. All are at iOS 9.0.2 (the new phones were 9.0.1)
All went smoothly, and all still have good speed, no anomalous behavior after a few days.
My wife's 4s I did too, just for fun (she got a new 6s) and it is S-L-U-G-G-I-S-H to the point of being non-responsive at times. You can click on an app and it just waits about 5-7 seconds, then launches it. Swiping from page to page of apps takes forever.
I was pleasantly surprised by how well the 5s came through it. I wanted iOS9 for upgradability of some of my key iPod apps. It is still quick and responsive. Not sure how much of that was the iOS upgrade, and how much might be related to removing 203 apps which I don't need on an iPod.
I did not update the iPad 3 to iOS9. It's use is fixed, and limited, and the apps I use are committed to continued support on iOS 8. It works great with iOS 8.
