> Cellebrite sells their lower-level devices to Apple directly for things like data transfer at Apple Stores.

Please substantiate that claim. Why would Apple need mystical third party devices to transfer data? They've designed both the user devices and the software, and they're both capable of exchanging data, and I'm sure Apple can do even more once they put the devices in diagnostic mode. What am I missing? What is Cellebrite providing here?

Do you have a link that talks about this in more detail?
