Thanks for the help. I used iphone explorer on an epub converted to mobi with calibre and could not get the ipad to sync with my android phone or my kindle. In fairness I may have confused amazon because I also changed the asin and the other exth record using mobi2mobi first.I then deleted and started over with the mobi using calibre but it wont sync

I shall try another book soon. I also have kindle v2.7 for the ipad, but I dont know if that would matter or not.
EDIT: FWIW After playing around with this some more, the only book that doesnt properly sync is the one where I manually went in and jacked with the ASIN and other settings
