[Preroll]

Maybe premature to ask this but I was wondering if future OS updates can be handled with DM instead of OTA. Being that the phone is new, I know there isn't a track record of this yet but curious to find out going forward if OS's can be downgraded like prior models. Guess I'll have to wait and see.

There is a check for updates option in Blackberry Link, the thing that kind of replaced DM.
One of the leaked OS was an executable (self loader) that worked, but didn't do a backup/restore.
