They built specialized tools to update iOS through the cardboard box without opening it before it goes on sale. I’m sure they can build something with a big “go” button if it’s important.
People aren’t debating whether or not Apple could theoretically find a way to transfer data between the devices they make and sell. The question here is if there is any evidence for the assertion that Apple buys Cellebrite devices in lieu of making their own solution for transferring data between the devices that they make and sell.
I really wonder how the wireless data transfer works.
