“The iPhone cannot be synced. An unknown error occurred (13019)”
We are noticing a growing trend on Jailbroken iPhone users who are experiencing a sync issue with itunes. The error code 13019 fix is somewhat a hit and miss. By now you have probably read about trying to de-selecting syncing voice memos and then attempting to sync them again. If that didnt work. its suggested to deselect syncing music, then videos, podcasts, etc. until a successful sync could be performed.
If all fails this might help…. Look through your voice memo app, if you find duplicate voice memos delete them and it should sync.
Please do NOT update your version of iTunes or firmware. as of now 4.0.2 firmware cannot be synced. Stick to what you know is working.
