Unlocked or not, if it is a VZW device, you will have to wait for VZW to approve of the update and push it out. The only way around this is to root your device and load a JB based ROM on the device yourself. Keep in mind that you will not be able to get good tech support from VZW should you do this and, if by some chance, you brick your device, there is a chance VZW will not honor your warranty.
In short, VZW has control over what OS is deployed on devices that run on their network. They do not have any control on what OS is deployed on Moto RAZR MAXX's that are activated on network's run by other carriers outside the US.
