After the slew of updates this week I'm no longer able to backup either my iPhone 4 or iPad. There are two errors:
"iTunes was unable to load data class information from Sync Services. Reconnect or try again later"
"iTunes could not back up the iPhone "Lee Hinde's iPhone" because the backup session failed."
Probably not coincidentally the existing backups don't show up in iTunes (preferences/devices).
My searching on these errors indicates they mostly seem to happen to Windows users and I'm on Mac 10.6.6.
Synching actually works. Odd. I.e., if I update an app on either device or the Mac, they are transferred as they should. It's the backup that's not happening.
I also updated XCode and the one similar issue I saw on Twitter was from a developer, so I'm leaning towards blaming XCode.
Did a Repair Disk Permissions.
Any tips appreciated.
