This happened to me. It finally stopped. I think this is what I did. I named my ppc the name I wanted it to be. I left that sync'd device on the desktop and renamed my ppc back to the name I wanted. I had upgraded from 3.8 and the ppc name was the same. So when it asked to delete a partnership, I deleted the WM_Name partnership. Sorry I can't be more specific, eventually it just stuck
