!!!!? iPhone 3.0 software

Hi there, after updating the software on my iPhone that you have removed all my music and not let me synchronize and everything about it is this>>>> *** The iPhone can not be synchronized. An unknown error occurred (13019). what I have to do to correct problem? Thanks

I would take him back to where you bought it and let them do the upgrade. I have heard of many people with this problem. The alternative is to do a hard reset and try the update again. Then see if you can synchronize.
