Does iPhone automatically back up in iTunes when updating the OS?
I had just installed iTunes and had sync'd my iPod so I then went ahead to synch my iPhone - When I plugged in my phone it said there is a software update available and do I want to update - I said yes. When it had finished I looked on my phone and I had lost everything - contacts, music, pics, vids Everything. So I suppose i'm asking if there is anything I can do to recover the lost content. In effect "Does iPhone automatically back up when updating the OS"?. Any help would be appreciated (not expecting joyous news).
