I am moving over to a mac and am wondering if it's possible to move my iphone backups from my Vista laptop to my MBP. My iPhone is jailbroken and I want to make sure I have an existing backup of my phone pre jailbreak. I could restore it on the vista machine, sync it to the mac, back up, and then re jailbreak, but it would be a far less hassle if it is possible to move those back ups over.
