"mob"??? I have no idea what that is. And, since you don't have a BB device, I'm totally lost as to how to help you.
In general, restoration of data requires access to a backup taken prior to the loss of the device on which the data resided. So, if this "mob" was previously backed up somewhere, then you might have access to the data via various tricks.
But, again, not knowing what a "mob" is, nor if/how you conducted any backups, it's pretty much impossible to give you any more detailed guidance.
