Motorola may give the Dev. version restore images
And reinstated warranties for those that requested dev. unlock codes:
Obviously this warranty thing doesn't help those that unlocked consumer devices, but the images are nice.
The RAZR M is not yet posted, but it is a 2012 Razr, so we'll have to wait and see.
EDIT: Hmm, but they do specifically list the other 3 and not the M, so maybe we won't see it....
