I have had my iPod touch for a few weeks now, but the other day it stopped syncing - partly. Let me explain: I can sync Music, Movies, Podcasts and Photos, it is only if I tick anything on the "Info" tab in Itunes that I get an error message. Means: If I want to sync address book, iCal, Mail accounts or bookmarks, iTunes starts syncing the music etc, but then spits out an errormessage when it gets to the latter: "iTunes could not sync mail accountsto the iPod because the sync serverfailed to sync the iPod" I then started up up the console to have a look what it wanted to tell me, here is what I got: Waiter has started running... 2008-06-19 15:17:41.449 AppleMobileSync998 CFLog (0): CFPropertyListCreateFromXMLData(): plist parse failed; the data is not proper UTF-8.

I found the above syncservices folder, and dragged it to the desktop to see what would happen. iTunes could still sync music, but for other data it would tell me this: "iTunes could not sync mail accountsto the iPod because an error occurred while pushing data from the iPod" So I quickly moved the folder back, and the same (original) errormessage returned. I am at loss what to do - reinstall iTunes? ARGH!
