Re: iPad 2 and iPhone 4S work perfectly with iOS 9.x
We have both a 4S and iPad 2 here in the household. Both seem to work as they always have done.
Are they slower than my shiny 6S? Yes
Would I like the adblocker option on the 4S? Yes
Should Apple allow and support the downgrading of the OS 1to -1 version? Yes.
