Cellebrite got its start with the UME, a phone memory transfer tool for carriers' (POS and support). Carrier-oriented tools are a major part of its operations, though there have been some talks about spinning this off to a separate company.

Cellebrite gets early access to phones NOT due to its forensics operations, but for UME, since carriers (and that's lots(!) of carriers worldwide) are very much interested in good consumer experience on the devices' launch day.

I actually doubt it's been particularly significant to its forensics operations.
