Had this problem a few months back when I flashed one of the Mighty ROMs. You have to call sprint, the sprint rep is going to get you to try all this stuff thats not going to work, tell them no thanks. Tell the sprint rep that he has to call telenav while your on the phone and tell them to renew your account. They are not going to want to do it, but it takes all of 5 min, you have to Demand that they do it. It took me 3 days to get it fixed, but have been working fine ever since.
