I downloaded iTunes 10.7 from the iTunes Store (to make sure I had the absolute latest version), and I still cannot add music to my iPhone 4s, or my kids' iPod Touch 4's. I can sync apps and onther info to these devices, but it lags indefinitely when I try to add new music (including podcasts) to any of these.
On a side note, I was able to sync my iPod nano (a couple of years old) without problem. It's the newer devices that are not allowing for the transfer of music.
Add another one to the list. Upgraded to 10.7 and now my iPhone 4s will not sync my music library.
****! I should have known better than to do an iTunes upgrade, but I don't even remember being asked!
This is unbelievably frustrating!!
Any help would be appreciated (especially talking to you APPLE!).
I did a 'work around' by starting to use iMatch again (to sync my music). I suspect that one of the issues was around syncing podcasts, which is now a separate app (with OS 6). Since upgrading my operating system on all devices, the problem does seem to be resolved. However, I have not tried to do any syncing of music to my iPhone 4s or iPad 2 (except for via iMatch).
Others struggling with this: make sure you upgrade to OS 6, and use iMatch (if you have it) to sync your music.
I have a similar problem with my iPad 3rd generation (which is brand new). I updated everything to make sure I was up to date and now when I try to sync music, iTunes crashes and I have to CtrlAltDelete to close it down. I can't even wi-fi sync as it just doesn't do anything, apart from wirelessly crash my iTunes xD
