Just been reading through the JB threads and I think when I get back from my holidays I'll give it a go. One question it raised though that I thought would be useful to know is how to backup my iPhone backup 
Let's say I wanted to do a rebuild of my PC, what do I need to make a copy of to make sure that once I reinstall windows and iTunes, my last backup is there and perfectly functional? Just as if nothing had happened.
Edit: Sorry, should have said, I'm on Win7
