I have my iPod touch on iOS 5.0.1 and I am using wifi sync. I still get this error on my iPod screen with a wired or wireless sync. The error that comes up on my iPod screen every time I sync is "4 items could not be synced. Please check iTunes for more information." When I look at iTunes there are no errors showing up on iTunes and I don't see iTunes try to sync anything and then stop or anything like that. If I sync manually instead of automatic and watch it, the error shows up on my iPod but iTunes says nothing. I also don't see anything missing on the iPod that it didn't sync so I don't know why I am getting this error. This is a minor annoyance and I want to know how to fix it. Thanks.
Got a tip for us?

i got the same errors, and they started happening when i turned on (then off) itunes match. i didn't know how to fix it, so i just yesterday restored my iphone to resolve the issue.

I have restored multiple times and it still gives me the same error.
I finally resolved this issue for myself by going into iTunes' Preferences, clicking on the Advanced tab, then clicking on both reset buttons: "Reset Warnings" and "Reset Caches".
Note, however, that I did this AFTER unchecking the sync checkboxes for every possible thing that I thought might be causing the problem: voice memos (which have been a HUGE syncing headache in the past), expired TV shows & movies, unnecessary music & books & podcasts, etc.
