First, thank you all for your comments and suggestions. Will try them later on this evening.

@DiapDealer - good suggestion however, I do know with 100% certainty that the book I am trying to sideload via iPhone Explorer or iPhone Folders is DRM free. My entire collection is DRM free as this is one of the first things I do to all books regardless of where I purchase them.

I do think you and Carol have a good suggestion in trying to re-convert the file in the latest version of Calibre (which I have) and trying to load it again. Most of my library was done prior to the latest version which now has synch ability as part of its functionality.

QUESTION: Do I just highlight the book I want to re-convert in Calibre and hit convert? I guess what i am asking is will the conversion process just override the last mobi version in Calibre or do I need add the book again (in mobi) and then re-convert.

Finally, once I have re-converted the book, should I add it again to my Kindle and the iPhone simultaneously since this is a new version of the book?

I feel very close so that is good news, especially with all the very smart people on this forum. I am positive this is going to work.
