music not syncing with iphone 4s

Yes, but it wasn't pretty.

After trying multiple remedies, some described here, with zero results, I was forced to wipe out the entire phone and restore it. This, after wiping out and reloading iTunes a few times.

After I got iTunes stabilized, and deselecting all music to be synced, I did a full restore of the phone, it's Apps. I then reloaded the music fresh.

It took the better part of three days to get the phone back to where I wanted.

Still feel it was a "unstable" iTunes update that was the cause.

Oh, I worked with two techs from Apple Tech support for better than 4 hrs. I got off the phone the last time trying a recommended solution that I had previously attempted with no result. That one didn't work either.

So , the solution that finally worked was a self inflicted nuking of both the PC 's iTunes, then the iPhone, starting from scratch.

I am so fed up with itunes. I also did a complete restore of my phone. Moved my itunes folder to an external drive Uninstalled itunes and reinstalled. Set up my phone as new. It worked as i redownloaded the music I purchased. Spent a good part of the night manually transferring some personal mp3s. No problem.. all synced well but way too many so I decided to resume in the morning. Today is a different story. It begins to sync but gets stuck and cancels. I thought maybe the problem was that I was using Copytrans. I read here somewhere that it leaves some kind of file that iTunes doesn't like but after starting fresh I'm not so sure.

Interestingly I used a different USB port and it's fine.. everything synced. Wonder how long this will work
