How often does Apple restock certified refurbished iPhone 14 Pros?
"I want to buy a certified refurbished iPhone 14 Pro, but it's only available in space black. Do you know how long it might take for the gold one to be back in stock?"
We are all users here......just like you. We have no way to know what Apple might do or when they might do it.
All that you can do is keep checking to see if what you want is available.
