One thing that I have seen in working with other phones in the past is that some store to the SIM, some store to the phone. I know when at AT&T, and you move to a new phone, they will check to ensure the contacts are copied from the phone to the SIM before they remove it. If you still have the old phone, they might still be there. If they are, you could take the SIM and copy to it, then try to Import again. Worth a try. Good luck.
