I wasn't clear enough. The tracks were all fine and would have played thru had I let them. However, I interrupted them by going to another track and then another after I listened enough to each one to satisfy my interest. While I was doing this, I soon realized that the tracks were disappearing as I clicked on the next selected track. This effect appeared to only happen with this album and in fact when I just now attempted to replicate more track loss, the remaining tracks would not disappear on this album either. Just before my initial post I had just checked that some random albums' tracks seemed to be complete and wouldn't disappear either. The lost tracks only occurred in one or two sessions with that one album. There is an extra issue. I have several cd albums that are listed under 'various' because the lead singer shared singing with some of her well known singing friends. This album is one of those, BUT I haven't lost tracks from a couple other 'various' albums I just checked (and had similarly scanned). If anyone knows where 'various' tracks go if they loose their association, they could be there I suppose. As usual, I hadn't thought to Google this issue until I posted. I found a 37 page active chat about this and similar track loss that began in 2009 and continues to the present. I suppose this could be a random general problem. I can always re-rip the cd but I was (and am) afraid that the problem will repeat. I am still wondering if I accidently clicked on some setting that hid the tracks so they wouldn't repeat and now should change a setting that will un-hide them.

try the forums at this site they are all knowing about ipod and itunes related stuff iLounge True but you must be very patient as it might take a week or more to get a response, re post if necessary after a couple days, it has worked for me.

Both phones will play MP3s. I play MP3s through iTunes all the time. The key difference between these phones is if you download music from the iTunes Music Store (as about 80% of people who download music legally do). If you do, the iTunes phone is the only one which will play that music directly because it is copy-protected. The other phone will require you to convert the iTunes music to MP3 (not a trivial task).

mikecowley- I disagree with the view that it isn't in Apple's interests to be helpful. My interpretation is that Apple is making it difficult for a person who can't prove that they don't have a stolen phone to get that phone activated. I prefer that position because it provides a strong disincentive to thieves, and that is in the best interests of customers as it provides all iPhone owners a lowered risk of theft and robbery. The OP's situation is unfortunate, because I believe her that it is a legitimately owned phone, but if Apple started making exceptions for all plausible stories then the value of their policy would be next to nil.
