This article may help. I believe it will move everything to a new drive or pc.
Poco, a quick, dumbnut question about iTunes: if I make a "backup" of my iPhone when I hook it up to iTunes, and if I screw things up within iTunes by synching incorrectly, etc., etc., can I
always get my apps, contacts, MP-3s, wi-fi settings, and other personal data back by using my "backup" to restore the phone???
Please understand what I'm asking. My iPhone has some incredible stuff on it, and
I KNOW that when I hook up to iTunes to synch music off my PC to it, iTunes will destroy my life. Will my "backup" save me? Thanks dude!
