I just got this together with an update to v12.0 on my iphone. My iphone update info said I can now cast my Go to my iphone. How do I do this? thanks.
I should imagine it's the same as it is for us android users.
You need to log into your Oculus App, enable bluetooth and pair with the Oculus Go, it should download the software update via the bluetooth.
The App needs to be connected to the internet to download the firmware update.
