Xylinx--How do you delete manually? I started with one problem. Followed various people's advice and now have 2 problems.
First problem--I downloaded MP3 version of books on tape. Two sets of the book, chapters all jumbled up, appeared on my iPhone under Music. I went to iTunes and only one version of the book appeared. I deleted it from my phone in iTunes. One version disappeared from the phone, but the second remained. It is nowhere to be found in iTunes, yet it remains under Music on my phone. It deleted it from Overdrive (which is how I got it into iTunes in the first place) and from a file I found on my computer. It is nowhere on my computer now, but still it does not delete from my iPhone.
Second problem--Following directions from others on this list, I unchecked and rechecked Sync only Checked, and turned off Show All Music, I now have two music albums on my phone that I didn't want to be there. I tried to delete them like I have always deleted music by clicking on them and hitting delete on my computer, but they do not delete. The check mark is grayed out, meaning it is inaccessible.
YIKES!!!!
