How do I get the iOS 9.4 Beta Update? Is there even a iOS 9.4 Beta Update.
iOS 9.4 Beta Update
Start with the 'resources' link above...then iOS, then downloads, then notice that there is no 9.4b at this time.
If you really want an iOS 9.4 beta, you'll have to come back later or explain why it's so important right now, at least.
Ah, rumors. Blogs are full of them. Must be all those demanding editors pushing for dirt.
Fall 2016?
AFAIK there is no such thing as public beta 9.4(yet)
