I have my install disks ready. I've never formatted my MBP before. What should I do? What software shall I use to make a backup? My main concern is if Mobileme from my iphone 4 somehow wipes all my contacts. I want to take precautions against this. I've also renamed files within Itunes. Are these permanent on their ID3 tags because I wouldn't want to renew them. I'd also love to have my website password chain list incase I forget a few logins.
