Article on Phandroid or something suggested the whole problem may be Google Wallet. Google doesn't want it's Nexus device touched, and VZW has a contractual agreement with a competing Wallet service. It's a bit hard to believe, but it could be the issue. Just can't imagine Google making such a stink over it, unless they view it as a line in the sand (i.e. do what you will with other devices, by HANDS-OFF our developer device), because it won't be that tough for customers who want to add Google Wallet to the Nexus (granted, for the majority they won't care or bother, which is the heart of unfair competition laws). But VZW hands may very well be tied on this issue and may have to work out a side agreement or settlement specifically for the Nexus with whoever they have that contract with.
