I normally sync my iPod 4G via USB as video content takes too long to transfer wirelessly. However since updating to iOS6 if I do try to sync wirelessly all the content is deleted from my iPod - music, video and podcasts are all gone. I have to plug it in a spend 90 minutes copying across the content again.
It seems as if the iPod is deleting all content before trying to resync it wirelessly, but it would be ludicrous if this was the intended functionality. Transfering 46GB would take forever.
Has anyone else encountered this and found a solution? All I have done is turned off option to sync via wi-fi to prevent this happening again.
