I have had trouble being able to listen to an audiobook that I downloaded from itunes into my Incredible. I have downloaded two different apps to expedite the process of syncing with itunes, which are "doubletwist" as well as "Ambling Book Player" but none of them will let me listen to this audiobook. When I look at the suffix it says MPEG-4 audio (protected) and I'm wondering if there is a way to be able to make this work from my Incredible? Any ideas??
