No promises, but from what I have read, that should not be an issue. Of course, if your phone currently has an AT&T ROM installed, for example, you will get an update for an AT&T device. Plug into Zune (Settings>Phone>Update) and check for updates rather than waiting for your phone to tell you an update is available.
