I currently have a 16 GB iPod Touch running 2.1, jailbroken. I am unsure whether it has been pwned or not (does pwned = jailbroken?), because it shows the Apple logo and not the pineapple when it boots. When I previously jailbroke, I installed 2.1 fresh from iTunes and then used QuickPwn on Windows. Now, I'm using Mac OS on an aluminum MacBook which I have heard has issues with DFU mode. What's the best way to upgrade from 2.1 jailbroken to 2.2 jailbroken without losing what's on the iPod (apps, music, email, notes, etc..)?
