Steve, can you try getting the service books extracted from another working BlackBerry device on MTS?
You can backup that working device, then use BBSAK to extract the service books and then load them to your device. Or, is that what you have already done?
If so, then I suspect this might be an issue of connectivity with your BIS account on MTS. Is that account setup already, you are sure? Can you login to it on your PC and create email push accounts? From there, you can click to send service books.
