It appears that iOS 9-point-anything does not work with the iPhone 4s and 5 models. I can get no data to work on messages, apps, etc. my voicemails are not visible. All previous updates worked perfectly. Prior ot 9 point anything. Apple says they can not figure this out, & the people at the Apple store don't know. After three years of happily using the iphone, I can not access the simplest of functions. Now Apple has tried three versions of 9 point o, and not successfully. Please get the engineers to repair, or allow us to go back to 8 point anything. that was flawless.
