I think m4b files are just aac files. So I would use iTunes to convert the mp3 to aac (set your import settings to acc, Ctrl+click on the file in the library and choose Convert). and then change the file extension and re-import into iTunes. See if that works and report back so we know.

Hi Gary,
The audiobook conversion worked, even though I have to rename the ID3 Tags.
