When syncing iphone to itunes does it back up contacts and photos automatically or do I have to specifically tell itunes to do that when I set up my iphone. Basically what has happened is that I had to do a "restore not from a backup". After doing this I lost all contacts and photos. I do however have a complete backup which includes itunes on a hard disc from a few days ago. Will Itunes have that information saved from a previous sync?
