But, yes, in either case, there shouldn't be a need to downgrade.No need to downgrade. The final beta (GM). Is the same, in most cases, as the public release.
I recall a couple of times when the GM was not the same as the public release - I think it was iOS 4 and iOS 9.No need to downgrade. The final beta (GM). Is the same, in most cases, as the public release.
