It looks like the new XPRT battery door is rubberized. Has anyone tried the XPRT battery door on the Pro? I hope it fits.
This might give you some insight. I know its nothing definitive about the battery cover specifically, but at the thread below they compare the size of the XPRT to the Droid Pro and how cases fit/etc. If I am understanding them correctly, it doesn't seem likely that the XPRT back will fit on the Droid Pro. Read for yourself and see what you think.
Case? - Android Forums
I just went down to Sprint to take a look. The XPRT has a smaller camera opening so the battery door would have to be modified to fit the Pro. The case is also thicker for the larger battery and I'll just stick with my Pro back cover.
