I just spent an hour or two with Apple people, starting with tech support for my new phone, and ending with tech support for Apple with an accelerated case due to lack of resolution. The gentleman I spoke with last, said that the feedback section of the Apple site is taken VERY seriously by the engineers. This guy (Bryan, I know you are watching now!) was the first one to go to the blog section here and read through some of the comments. I followed his instructions and left a lengthy feedback comment and linking this thread to the feedback so the engineers could look at what everyone had sourced out. The people on the front lines are still recommending that we sync our phones, etc., which obviously I am not going to do until we have a legitimate fix for this issue. I also did three repair/reboots and then a complete re-installation of ITunes and almost ALL of my music will not play, not even ITunes-purchased music. I always "deselect" the 128kbps downgrade option; it would have been nice if my fix had been that simple!
I'd rather not do a rollback to another version as I have a new IPhone I'd like to use the ICloud with, and that requires a working 10.5 with my OS, namely..said Windows XP.
Here's the link to feedback:

The more actual feedback they get, the better for us, I think. I was able to talk to three different people at Apple today, and they do have a phone number. If your dvice is out of warranty, then just give comprehensive feedback. I listed mine as "compatibility issues" because, they are. If your device is still under warranty, use that phone number to air your issue if you will. Yes it is time consuming, but I think ultimately, worth it.
